4. Characterization of defects

4.1 Image of a dislocation (contrast optimization)

Channelling is achieved for a family of hkl planes when the untilted incident beam falls on the edge of the band (hkl), ideally for s > 0 and far from the intersection of another band edge so that only one diffraction condition is satisfied .

Dislocation images often have a bright side and a dark side (figure
