High Quality Content by WIKIPEDIA articles! High-resolution transmission electron microscopy (HRTEM) is an imaging mode of the transmission electron microscope (TEM) that allows the imaging of the crystallographic structure of a sample at an atomic scale. Because of its high resolution, it is a valuable tool to study nanoscale properties of crystalline material such as semiconductors and metals. At present, the highest resolution realised is 0.47 angstroms (0.047 nm) with double aberration-corrected JEOL R005, Cold Field Emission Gun TEM, at Tokyo Institut of Technology. At these small scales, individual atoms and crystalline defects can be imaged. Since all crystal structures are 3-dimensional, it may be necessary to combine several views of the crystal, taken from different angles, into a 3D map. This technique is called electron crystallography. Данное издание представляет собой компиляцию сведений, находящихся в свободном доступе в среде Интернет в целом, и в информационном...
