• Pursuing Band-like Transport in Colloidal Quantum Dot Assemblies

  Charge-carrier transport in semiconductor colloidal quantum dot (CQD) solids has been the subject of extensive debate and investigation for more than a decade. Understanding the underlying transport mechanisms in CQD assemblies is critical for unlocking their full potential in optoelectronic applications. To date, a widely accepted view holds that carrier transport in conventional ligand-capped glassy CQD solids is a non-adiabatic hopping process, supported by both experimental observations and theoretical models. In contrast, recent advances have enabled the self-assembly of CQDs into long-range-ordered superlattices with epitaxial connections between neighboring QDs. These superlattices are expected by many to exhibit band-like transport, potentially overcoming the limitations of hopping conduction in disordered systems. However, definitive experimental evidence and a comprehensive theoretical framework for charge transport in such highly ordered structures remain lacking. While the formation mechanisms of these superlattices have been widely explored, this Perspective aims to provide insight into the current understanding of charge-carrier transport in epitaxially connected CQD superlattices.

• High-Performance Photodetectors of Quasi-2-Dimensional Epitaxially-Connected Quantum Dot Superlattices

  Colloidal semiconductor quantum dots (QDs) are among the promising materials for optoelectronic device applications, including photodetectors. Their size-tunable bandgap enables wide-range wavelength photodetection from the visible to the mid-infrared regime. Most recently, the realization of epitaxially-connected quantum dot superlattices (QDSLs) addresses one of the critical challenges associated with assemblies of QDs and their electronic transport. These epitaxially-connected QDSLs demonstrated the possibility of delocalized charge transport, which could improve the electrical transport performance of QD-based devices. On the other hand, delocalized charge carriers might affect the quantum confinement effect, potentially reducing the merits of QDs for optoelectronic device performance. Here, we demonstrate high-performance photodetectors based on a monolayer of quasi-2D epitaxially connected PbS QDSLs, exhibiting higher responsivity and detectivity than those of conventional short-ligand-capped QD assemblies. The remarkable photodetection enhancement can be indicated from several aspects: (i) the light intensity-dependent characteristics reveal evidence of a low trap density within the epitaxially-connected superlattice, (ii) the time-resolved measurements show a faster response time and a two-step charge carrier dynamic, (iii) the wavelength-dependent analysis further suggests the occurrence of multiple exciton generation under high-energy photon excitation. These findings establish the epitaxially-connected QDSL as an optoelectronic metamaterial, an up-and-coming candidate for next-generation, high-performance photodetectors.

  AgBiS2 has emerged as a promising environmentally friendly nanocrystal (NC) for optoelectronic applications due to its broad absorption spectrum in the visible and near-infrared regions. However, a performance ceiling has hindered the development of AgBiS2-based solar cells, with power conversion efficiencies (PCE) remaining stagnant at 9–10%. This limitation arises from a lack of understanding of its fundamental properties, such as its crystal structure and electronic properties, which are crucial for further optimisation. Here, we focus on a comprehensive investigation of the synthesis and formation of AgBiS2 NCs. Utilising Rietveld refinement, the crystallographic structure and phase purity are meticulously analysed, ensuring precise insights into the material's formation pathways. Furthermore, the constructed phase diagram of the Ag–Bi–S system reveals the threshold temperature at 160 °C to obtain pristine AgBiS2 NCs, while below that, Ag2S NCs are dominant. Density of states (DOS) analysis shows a similar bandgap with an experimental result of 0.8 eV, confirming the semiconductor properties. High-performance photodetectors of AgBiS2 NCs are demonstrated, exhibiting high responsivity, although only using a few monolayers of the nanocrystal assemblies. These results bridge the knowledge gap in AgBiS2 formation mechanisms and electronic behaviour, establishing a robust foundation to enhance its optoelectronic performance and integrate it into advanced device architectures.

  Tin chalcogenide nanocrystals (NCs), particularly tin(II) sulfide (SnS), hold promise for environmentally benign optoelectronic applications. However, challenges such as scalable synthesis, susceptibility to oxidation, and unclear reaction mechanisms hinder further research and limit the exploration of their electronic properties. This study presents a single ligand-controlled hot-injection strategy to synthesize monodisperse pi-SnS NCs (4.7-8.5 nm) with unprecedented size uniformity and long-term stability (>1 year). By systematically optimizing precursor mole ratios (Sn/S up to 4:1) and adjusting solvent composition (reducing 1-octadecene (ODE) volume to <= 1.84 mL), we achieved narrow size distributions (standard deviation of 0.4-0.7 nm) and suppressed phase impurities, overcoming the limitations of conventional hot-injection methods that rely on multiple ligands. The synthesis advances demonstrated optoelectronic properties: size-dependent quantum confinement (band gap tuning via NC diameter) and p-type behavior in NC thin films treated with ligand 1,2-ethanedithiol (EDT). These findings provide a scalable, single-ligand synthesis framework for pi-SnS NCs, resolving challenges in reproducibility and stability while opening pathways for eco-friendly NC-based electronics.

• Charge carrier injection and extraction of colloidal quantum dot assemblies: a perspective for optoelectronic devices
  Satria Zulkarnaen Bisri
  Journal of Information Display
  Taylor & Francis
  Efficient charge injection and transport are fundamental challenges in colloidal quantum dots (CQD) optoelectronic devices such as photodetectors, solar cells, and displays. Unlike traditional semiconductors, charge transport in QD films is governed by hopping mechanisms, influenced by interdot coupling, ligand chemistry, and defect states. However, many aspects of these processes remain poorly understood. The interplay between charge injection, interfacial trap states, and carrier mobility introduces complex loss pathways that hinder performance. Many key unanswered questions remain, including the influence of different QD compositions, ligand environments, and orders near the interface on charge transport. Here, we discuss the challenges that should be investigated and solved in the near future. Addressing these knowledge gaps through advanced spectroscopy, transport studies, and interfacial engineering will be crucial for unlocking the full potential of CQD for transport-based optoelectronic devices, including electroluminescence displays, paving the way for high-efficiency, low-power, and long-lifetime devices.

  The growing need for high-performance computing continues to drive improvement in circuit and device technologies, particularly with respect to speed and power efficiency. Device scaling remains the most effective strategy for meeting circuit performance requirements while reducing power consumption. Thanks to their solution processability, colloidal semiconductor quantum dots (QDs) are highly suitable for device miniaturisation as quantum information science platforms. Quantum mechanical effects must be carefully considered when designing nanometre-scale electronic devices (i.e., transistors) that incorporate a single QD. Here, we demonstrate a resonant tunnelling transistor (RTT) based on a single lead sulfide (PbS) QD anchored by a bidentate ligand molecule attached to heteroepitaxial spherical Au/Pt nanogap electrodes. Five negative differential resistances (NDRs) were observed at both positive and negative drain voltages in output characteristics, which could be attributed to the formation of a double-barrier “quantum well” structure with the strong Fermi level pinning of the discrete energy level of the QD to one electrode. Furthermore, these NDRs could be tuned by applying a gate electric field, which will become one of the keys for enabling quantum and neuromorphic electronics. This demonstration of single PbS-QD-based RTTs paves the way for sub-10 nm solution-processable quantum electronic devices.

  A crucial factor for the success of hydrogen (H2) as the backbone of energy transformation is the efficient production of green H2, especially through the solar-to-hydrogen process. The key to greatly improving photocatalytic H2 evolution lies in the design of catalyst materials, where nanostructure engineering plays a pivotal role in driving these advancements. Engineering the nanostructure of TiO2 as a photocatalyst can significantly drive up its H2 evolution performance by benefiting from the created large surface area and the suppressed charge recombination. Here we show the synthesis of dendritic fibrous nano silica–titania (DFNST) using in situ seed-microemulsion crystallization which demonstrate high performance H2 evolution even without the addition of any cocatalyst. The impact of different TiO2 crystalline phases on the formation of the DFNST composites and their H2 photogeneration performance under visible light is thoroughly investigated. Synthesizing the composites using a low-temperature reflux method enhances the textural properties of the TiO2. Significant influence of the inclusion of anatase, rutile, and mixed rutile–anatase TiO2 phases on the morphology, optical, and catalytic characteristics of the DFNST is revealed. The formation of Si–O–Ti bonds acting as electron transfer bridges between TiO2 and the SiO2 framework boosts the photocatalytic activity. On the other hand, the increased hydrophilicity in DFNSTa and DFNSTm enhanced water molecule uptake, contributing to efficient H2 ion generation and interaction with electrons to produce H2. Based on our current finding, the surface area plays a key role in enhancing the photocatalytic H2 evolution by providing the surface active sites, which supports other conditions, such as mesoporosity, band gap, and hydrophilicity, and is combined with defect control for facilitating effective charge carrier transfer and separation in the homojunction system, as observed in the mixed-phase DFNSTm that exhibit the highest H2 photogeneration rate.

  Colloidal quantum dots (CQDs) show unique properties that distinguish them from their bulk form, the so-called quantum confinement effects. This feature manifests in tunable size-dependent band gaps and discrete energy levels, resulting in distinct optical and electronic properties. The investigation direction of colloidal quantum dots (CQDs) materials has started switching from high-performing materials based on Pb and Cd, which raise concerns regarding their toxicity, to more environmentally friendly compounds, such as AgBiS2. After the first breakthrough in solar cell application in 2016, the development of AgBiS2 QDs has been relatively slow, and many of the fundamental physical and chemical properties of this material are still unknown. Investigating the growth of AgBiS2 QDs is essential to understanding the fundamental properties that can improve this material’s performance. This review comprehensively summarizes the synthesis strategies, ligand choice, and solar cell fabrication of AgBiS2 QDs. The development of PbS QDs is also highlighted as the foundation for improving the quality and performance of AgBiS2 QD. Furthermore, we prospectively discuss the future direction of AgBiS2 QD and its use for solar cell applications.

  The high surface-area-to-volume ratio of colloidal quantum dots (QDs) positions them as promising materials for high-performance supercapacitor electrodes. However, the challenge lies in achieving a highly accessible surface area, while maintaining good electrical conductivity. An efficient supercapacitor demands a dense yet highly porous structure that facilitates efficient ion–surface interactions and supports fast charge mobility. Here we demonstrate the successful development of additive-free ultrahigh energy density electric double-layer capacitors based on quantum dot hierarchical nanopore (QDHN) structures. Lead sulfide QDs are assembled into QDHN structures that strike a balance between electrical conductivity and efficient ion diffusion by employing meticulous control over inter-QD distances without any additives. Using ionic liquid as the electrolyte, the high-voltage ultrathin-film microsupercapacitors achieve a remarkable combination of volumetric energy density (95.6 mWh/cm^3) and power density (13.5 W/cm^3). This achievement is attributed to the intrinsic capability of QDHN structures to accumulate charge carriers efficiently. These findings introduce innovative concepts for leveraging colloidal nanomaterials in the advancement of high-performance energy storage devices.

  Colloidal quantum dots are sub-10 nm semiconductors treated with liquid processes, rendering them attractive candidates for single-electron transistors operating at high temperatures. However, there have been few reports on single-electron transistors using colloidal quantum dots due to the difficulty in fabrication. In this work, we fabricated single-electron transistors using single oleic acid-capped PbS quantum dot coupled to nanogap metal electrodes and measured single-electron tunneling. We observed dot size-dependent carrier transport, orbital-dependent electron charging energy and conductance, electric field modulation of the electron confinement potential, and the Kondo effect, which provide nanoscopic insights into carrier transport through single colloidal quantum dots. Moreover, the large charging energy in small quantum dots enables single-electron transistor operation even at room temperature. These findings, as well as the commercial availability and high stability, make PbS quantum dots promising for the development of quantum information and optoelectronic devices, particularly room-temperature single-electron transistors with excellent optical properties.

  Semiconducting colloidal quantum dots and their assemblies exhibit superior optical properties owing to the quantum confinement effect. Thus, they are attracting tremendous interest from fundamental research to commercial applications. However, the electrical conducting properties remain detrimental predominantly due to the orientational disorder of quantum dots in the assembly. Here we report high conductivity and the consequent metallic behaviour of semiconducting colloidal quantum dots of lead sulphide. Precise facet orientation control to forming highly-ordered quasi-2-dimensional epitaxially-connected quantum dot superlattices is vital for high conductivity. The intrinsically high mobility over 10 cm^2 V^−1 s^−1 and temperature-independent behaviour proved the high potential of semiconductor quantum dots for electrical conducting properties. Furthermore, the continuously tunable subband filling will enable quantum dot superlattices to be a future platform for emerging physical properties investigations, such as strongly correlated and topological states, as demonstrated in the moiré superlattices of twisted bilayer graphene.

• Enhancing quantum capacitance of iron sulfide supercapacitor through defect-engineering: A first-principles calculation

  Electrochimica Acta
  PERGAMON-ELSEVIER SCIENCE LTD
  Quantum capacitance (CQ) has recently emerged as a solution for the saturated growth of supercapacitor performances. The CQ depends on the density of states of the electrode materials, which could be tuned by several approaches (i.e., introducing dopants). In this case, a transition metal sulfide material with a narrow band gap, such as hexagonal iron sulfide (h-FeS), has enormous advantages. In this study, we predict p-type defect importance in the h-FeS structure on capacitance enhancement through the quantum capacitance mechanism. From the first-principle calculation, the Cr-doped h-FeS (FeS:Cr) anode results in integrated quantum capacitance (Cint Q ) of 1043 F/g, or 27 times more than pristine h-FeS. From the formation energy calculation, the Cr-doped structure has a lot of stable charged states enabling additional redox-related capacitance. As dopant concentration increased, the Cint Q is found to increase but then saturate due to delocalized state appearances. These findings imply that a first-principles understanding is essential to predict the enhanced capacitance properties on h-FeS and TMS supercapacitors.

  Organometal halide perovskites have been gaining tremendous attention for their potential application as optoelectronic devices, owing to their excellent optical and electronic properties. This work fabricated MAPbBr3/ PMMA composite film with bright green emission via a simple drop-casting method. It is found that when MAPbBr3 were combined with PMMA, PL peak position and edge absorption spectra exhibit a redshift phenomenon. Comprehensive characterizations using x-ray diffraction (XRD) and transmission electron microscope (TEM) suggested that this phenomenon possibly corresponded to the dielectric screening and strain of perovskite crystal induced by the presence of PMMA. Understanding this redshift phenomenon could be beneficial for developing high color purity optoelectronic devices. A potential application of the prepared film as a green down-converter is also demonstrated. Applying the MAPbBr3/PMMA film on a UV LED has successfully generated green color at (0.21, 0.71), close to the green color standards, i.e., NTSC 1953 and Adobe RGB 98. This result suggests that MAPbBr3 perovskite nanoplatelets/PMMA composite films have great potential for lightemitting device applications.

  Colloidal quantum dot (QD) solids are materials that exploit the quantum confinement properties of the constituent nanocrystals. Significant progress in QD optoelectronic devices has been made mainly using compounds with concerning high degree of toxicity for practical applications. Sn-chalcogenides are among the possible environmentally benign alternatives the bulks of which have demonstrated intriguing properties for energy devices. Nanostructuring these Sn-chalcogenides may create variations in their crystal structures and properties. Here, we demonstrate robust quantum confinement effects in small-diameter cubic SnS colloidal nanocrystals (NCs) and their potential exploitation for high-performance optoelectronic devices. Well-controlled production of cubic SnS colloidal NCs with a 4-10 nm diameter is established by developing a one-pot synthesis procedure in an inert condition that allows Sn complexation with only a single type of ligand molecule. The analyses of the X-ray diffractogram and transmission electron micrograph revealed that the structure of NCs is the so-called pi-type chiral and cubic structures. These NCs behave as quantum dots, exhibiting a quantum confinement effect with strong variations of energy band gaps by size. The photodetectors of the SnS NCs exhibit high responsivity comparable to the other established QD systems, although the channels are made only from a single or few layer(s). This new compound will open new pathways for establishing environmentally safe and high-performance QD optoelectronic and photocatalysis devices.
