Quantitative analysis of ultrathin doping layers in semiconductors using high-angle annular dark field images.
It is well known that the high-angle annular dark field (HAADF) technique in scanning transmission electron microscopy is an incoherent imaging process in the lateral (xy) plane. However, as a consequence of the existence of partial coherence in the z direction, accurate quantitative interpretation of image intensity is difficult. The effects of coherence in the z direction can be reduced by in...
متن کاملTowards a Uniform Model for Lattice Defect Image Simulations
For more than seven decades, diffraction contrast in the TEM has been used for the study of both linear and planar lattice defects, such as dislocations, stacking faults, anti-phase boundaries, and so on. In recent years, several alternative approaches for defect imaging have become available: using a standard annular dark field detector, the STEM diffraction contrast image (DCI) mode produces ...
متن کاملDirect oxygen imaging within a ceramic interface, with some observations upon the dark contrast at the grain boundary.
Annular bright field scanning transmission electron microscopy, which has recently been established to produce directly interpretable images with both light and heavier atomic columns visible simultaneously, is shown to allow directly interpretable imaging of the oxygen columns within the Σ13[12¯10](101¯4) pyramidal twin grain boundary in α-Al(2)O(3). By using information in the high-angle annu...
متن کاملTowards quantitative analysis of core-shell catalyst nano-particles by aberration corrected high angle annular dark field STEM and EDX
One of the most useful and apparently straightforward attributes of annular darkfield (ADF) STEM imaging is the ability to image heavy atoms on relatively light substrates using Z-contrast (High-Angle ADF) imaging. From multislice calculations, however, some isolated heavy atoms, e.g. Re, can go undetected in a thin Co matrix in standard aberrationcorrected HAADF-STEM imaging of catalyst nanopa...
متن کاملNanoscale characterization of gold nanoparticles created by in situ reduction at a polymeric surface.
Transmission Electron Microscopy is used as a quantitative method to measure the shapes, sizes and volumes of gold nanoparticles created at a polymeric surface by three different in situ synthesis methods. The atomic number contrast (Z-contrast) imaging technique reveals nanoparticles which are formed on the surface of the polymer. However, with certain reducing agents, the gold nanoparticles a...
متن کاملIn Situ HAADF-STEM Imaging and Tomography of AuIr Bimetallic Catalysts
High-angle annular dark field (HAADF) STEM is an indispensable technique for analyzing heterogeneous catalysts, in particular those comprising high atomic number (Z) metallic nanoparticles (NPs) dispersed on low-Z supports. Readily interpretable atomic-scale Z-contrast imaging with high spatial resolution spectroscopy, including X-ray energy dispersive spectroscopy (EDS) and electron energy los...
