4D-STEM Microscopes Take Candid Snapshots of Atomic 'Nehborhoods'

atom4dRecent advances in hh-speed pixelated electron detectors have substantially facilitated the implementation of four-dimensional scanning transmission electron microscopy (4D-STEM). A critical application of 4DW e can directly see the hidden world of atoms thanks to electron microscopes, first developed in the 1930s. , electron microscopes, which use beams of electrons to
