The key principles behind electron diffraction are: SAED is a technique used in transmission electron microscopy (TEM) to obtain diffraction patterns from specific regions of a sample. A selected area ...

High Resolution TEM (HRTEM) to identify lattice spacings less than 0.15 nm Crystallographic phase analysis in Diffraction mode: Selected Area Electron Diffraction (SAD) from a minimum area of 200 nm ...

This course covers some of the more advanced topics in electron microscopy. The primary focus will be on imaging theory (relevant to HREM and STEM) and dynamical diffraction, the later focusing on the ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...
