Abstract
A special case of the x-ray multiple diffraction phenomenon, the Bra,og
surface diffraction (BSD), has been investigated under lattice damage
due to ion implantation in GaAs (001) samples. The BSD profile is very
sensitive to the diffraction regime (dynamical or kinematical) and
provides information regarding crystalline perfection and lattice
strains in both directions-parallel and perpendicular-to the sample
surface. Results from grazing-incidence x-ray diffraction and are also
reported. (C) 1997 American Institute of Physics.
