• Evolution of the formation of AgBiS2 colloidal nanocrystals for optoelectronic devices

  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 degrees 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.

• Visualization of the lamellar structure of polyvinylidene fluoride using phase-plate scanning transmission electron microscopy

  ELSEVIER SCI LTD
  Polyvinylidene fluoride (PVDF) is a crystalline polymer well-known for its excellent piezoelectric properties, flexibility, chemical resistance, heat resistance, and mechanical strength. PVDF exhibits crystal polymorphisms, with five reported crystal structures. Among these, the n-type structure has attracted much interest due to its superior piezoelectric properties; however, the details of its piezoelectric mechanism remain unclear. It is essential to evaluate the structure of PVDF at the nanoscale to elucidate its piezoelectric mechanism. In this study, as a first step toward elucidating its piezoelectric properties, we employed phase-plate scanning transmission electron microscopy (P-STEM) to observe heat-elongated PVDF. P-STEM is particularly effective in examining materials composed of light elements. We successfully visualized the lamellar structure, which was characterized by a layered arrangement of crystalline and amorphous regions. The period of the lamellar structure was approximately 7 nm, which was in good agreement with the results of small-angle X-ray scattering studies. In addition, high-magnification P-STEM images revealed that bundle-like structures oriented in the elongation direction were likely crystalline regions. This result indicates that P-STEM provides detailed local information regarding the orientation of the PVDF polymer chains.

• Effect of the surrounding environment on electron beam irradiation damage of enhanced green fluorescent protein

  Ultramicroscopy
  ELSEVIER
  Fluorescent proteins exhibit fluorescence and photoconversion, which are used to study biological phenomena. Among these, enhanced green fluorescent protein (EGFP) emits cathodoluminescence when irradiated with electron beams; this phenomenon has numerous applications in new research tools for biological phenomena. However, bleaching during electron irradiation is a major problem. Generally, the presence of water is important for biological samples, and structural observations are often performed under cryogenic conditions. One of the advantages of cryogenic conditions is the stabilization of the sample due to cooling. However, it is unclear which factor is more effective: the presence of water molecules or cryogenic preservation. To explore the stabilizing factors of the sample structure, we prepared four environments around the sample-dry at room temperature, wet at room temperature, dry at low temperature, and under cryogenic conditions-and investigated the electron beam irradiation damage by measuring the fluorescence emission spectra. Emission intensity from EGFP was attenuated, and the peak was red-shifted by electron beam irradiation; however, the intensity attenuation was fast under dry conditions at low temperature and slow under wet conditions at room temperature. These results imply that sample cooling has no significant effect on the stability of the EGFP chromophore and that the presence of water molecules is extremely important.

• Application of Hilbert-differential phase contrast to scanning transmission electron microscopy

  OXFORD UNIV PRESS
  We report a novel class of scanning transmission electron microscopy with Hilbert-differential phase contrast (HDP-STEM) that displays nanostructures of thin samples in a topographical manner. A semicircular pi-phase plate (PP) was used as an optical device for manipulating electron waves in HDP-STEM. This is the different design from the Zernike PP used in our previous phase plate STEM (P-STEM), but both must be placed in the front focal plane of the condenser lens. HDP-STEM images of multiwalled carbon nanotubes showed higher contrast than those obtained by conventional bright-field STEM. As the PP of the HDP-STEM is nonsymmetrical, several different images were obtained by changing the detection conditions. A two-dimensional electron detector was also used to remove the scattering contrast component in the same way as with the Zernike PP and obtain an image containing only (differential) phase contrast.

• First step toward complex observations by 4D-STEM with phase plate
  Togashi, Mayu; Minoda, Hiroki
  ULTRAMICROSCOPY
  ELSEVIER
  Quantitative measurements by electron microscopy are becoming increasingly important because we are often concerned with establishing quantitative relationships between the properties and structures of materials. This paper presents a method to derive the scattering and phase contrast components from scanning transmission electron microscope (STEM) images using a phase plate and two-dimensional electron detector and to quanti-tatively evaluate the amount of phase modulation. The phase-contrast transfer function (PCTF) modifies the phase contrast because it is not unity over all spatial frequency regions; therefore, the amount of phase modu-lation observed in the image becomes smaller than the actual value. We applied a filter function to the Fourier transform of image to perform PCTF correction and evaluated the phase modulation of the electron waves, which was quantitatively agreement with the values expected from the thickness estimated from the scattering contrast within 20% error. So far, few quantitative discussions on phase modulation have been conducted. Although the accuracy needs to be improved, this method is the first step toward quantitative complex observations.

  A two-dimensional (2D) detector was used to construct phase plate STEM (P-STEM) images. Phase-contrast can be enhanced by the electron intensity inside the hole region of a thin film phase plate. The electron intensity outside the hole region also provides a dark image contrast, which is inconsistent with the weak phase object approximation. We consider that both images have scattering effects that provide a dark contrast. Therefore, scattering contrast was derived by summing these two images, and scattering effects were subtracted from each image to display negative and positive phase contrast. The resultant images are consistent with the weak phase object approximation. These results propose separating scattering (electron amplitude) and phase-contrast (electron phase) using P-STEM, along with a two-dimensional electron detector.

  Green fluorescent protein (GFP) emits light when irradiated by not only light but also electrons. This electron-induced light emission called cathodoluminescence (CL) can be used to realize a high-resolution light emission microscopy based on the irradiation of a very narrow electron beam. To implement CL mapping in life sciences the investigation of the damage resistance of GFP to electron irradiation needs to be clarified. In this study, we investigated the electron radiation damage to GFP by analyzing the change in the CL intensity during electron beam irradiation. Since some of the CL spectra changed in shape during electron irradiation, the change in the intensity between 585 and 605 nm were measured. The characteristic doses at different electron current densities and electron energies were investigated. The characteristic dose of EGFP is much larger than that of coronene, which is one of the stable organic molecules against the electron beam irradiation.

• Cathodoluminescence of green fluorescent protein exhibits the redshifted spectrum and the robustness

  SCIENTIFIC REPORTS
  NATURE RESEARCH
  Green fluorescent protein (GFP) and its variants are an essential tool for visualizing functional units in biomaterials. This is achieved by the fascinating optical properties of them. Here, we report novel optical properties of enhanced GFP (EGFP), which is one of widely used engineered variants of the wild-type GFP. We study the electron-beam-induced luminescence, which is known as cathodoluminescence (CL), using the hybrid light and transmission electron microscope. Surprisingly, even from the same specimen, we observe a completely different dependences of the fluorescence and CL on the electron beam irradiation. Since light emission is normally independent of whether an electron is excited to the upper level by light or by electron beam, this difference is quite peculiar. We conclude that the electron beam irradiation causes the local generation of a new redshifted form of EGFP and CL is preferentially emitted from it. In addition, we also find that the redshifted form is rather robust to electron bombardment. These remarkable properties can be utilized for three-dimensional reconstruction without electron staining in focused ion beam/scanning electron microscopy technology and provide significant potential for simultaneously observing the functional information specified by super-resolution CL imaging and the structural information at the molecular level obtained by electron microscope.

  Water is an essential constituent of all biological materials as well as many non-biological materials. Not only the removal of water may result in undesirable morphological and structure change, the inability to sustain the hydrated conditions in the microscope also prevents the study of reactions which take place in aqueous environment. In order to overcome these problems we used wet environmental-cell transmission electron microscopy TEM (WETEM). Conventional TEM of dry smectite showed well-defined particle outlines (but without a specific shape) and typical smectite aggregates. Selected area electron diffraction (SAD) of dry particles showed stacking of smectite particles (i.e., aggregate) in very clear dot and ring patterns. In contrast, WETEM depicted well-dispersed clay particles showing a variety of different particle shapes. Analysis of SAD patterns obtained from dry and hydrated states illustrated a lattice change in different environments. The small lattice expansion in (h k 0) resulted from the expansion of the (0 0 1) plane resulting from the addition of water molecules in the crystal along the c-axis.

  Visualizing materials composed of light elements is difficult, and the development of an imaging method that enhances the phase contrast of such materials has been of much interest. In this study, we demonstrate phase-plate scanning transmission electron microscopy (P-STEM), which we developed recently, and its application to nanomaterials. An amorphous carbon film with a small hole in its center was used to control the phase of incident electron waves, and the phase-contrast transfer function (PCTF) was modified from sine-type to cosine-type. The modification of the PCTF enhances image contrast with a spatial frequency below 1 nm(-1). The PCTF for P-STEM with a spatial frequency below 1 nm(-1) is about three times stronger than that of bright field STEM. The ratio obtained using power spectra is consistent with the result obtained from images of quantum dots. The image contrast of biological materials was also enhanced by P-STEM.
