Electron backscatter diffraction (EBSD) is commonly discussed as diffraction phenomenon. In one of his last contributions, one of the fathers of EBSD, Oliver C. Wells, pointed out in 2012:
EBSP is commonly referred to as electron backscatter diffraction (EBSD) or
backscatter Kikuchi diffraction (BKD) most likely due to its relevance to Kikuchi patterns but Wells in ( Wells, O.C., “Comparison of Different Models for the Generation of Electron Backscattering Patterns in the Scanning Electron
Microscope,” Scanning 21, 368-371 (1999). ) has pointed out that the mechanism of EBSP formation is channeling and not diffraction.
