Anomalous X‐Ray Transmission Studies in Indium Antimonide: Surface Damage

Nearly perfect indium antimonide single crystals were studied by x‐ray anomalous transmission using silver Kα radiation and {220} reflections. The depth of abrasion‐induced surface damage was determined using the diffracted integrated intensities. The depth of damage was found to be greater on the B than on the A surfaces for the same amount of abrasion. For unidirectional abrasion the direction of the strain corresponded to the direction of abrasion, but some directional strain was also present when the abrasion was not unidirectional. The measured rocking curve half‐widths were not affected by severe surface abrasion. The effective absorption coefficient was measured to be 10.3 ± 1 cm−1.
