Kikuchi lines (physics)

Kikuchi lines are a phenomenon observed in electron diffraction patterns, particularly in materials science and crystallography when analyzing the structures of crystalline materials using techniques such as electron backscatter diffraction (EBSD) or transmission electron microscopy (TEM). They appear as bands or lines in the diffraction pattern and are an important feature for understanding the crystalline structure and orientation of the material being studied. These lines result from the inelastic scattering of electrons and the interaction of the electron beam with the periodic lattice structure of the crystal.
