Electron backscatter diffraction (EBSD)

Two different electron microscopes with EBSD detectors, provides both high speed and high resolution.

Electron backscatter diffraction is a common method of characterizing microstructure, crystal structure, orientation of the crystallite and local strain measured on material surfaces. This tool has increasingly become a common accessory to the scanning electron microscopes. This method is based on the Kikuchi diffraction pattern that forms as a result of incident electrons being inelastically scattered through atomic planes of the crystalline material.

The resulting Kikuchi pattern is matched with a bank of calculated Kikuchi patterns from different candidate phases. In our lab, we have two different FEG SEMs with EBSD detectors. Bruker’s e-Flash detector on JEOL 7800F with a high bright FEG source and Oxford Instruments Symmetry CMOS EBSD detector on Nova600 Nanolab FIB-SEM are providing both high speed and high resolution.
