Absorption‐induced enhancement of X‐ray contrast by soft X‐ray emissions

Contrast in atomically‐resolved EDX elemental mapping in real space or in reciprocal space channelling patterns, derived from characteristic X‐ray emissions excited by a given probe, is generated by the variation in emission rate as the incident wave function is scanned over the target atoms in a crystal. This is achieved either by raster scanning a focused coherent probe in real space at a fixed orientation (conventional EDX mapping), or by a …
