Vv. Aristov et al., POSSIBILITIES OF X-RAY INTERFERENCE DIFFRACTOMETRY FOR THE RECONSTRUCTION OF 2-DIMENSIONAL LATTICE DEFORMATION PROFILES IN CRYSTALS, Journal of physics. D, Applied physics, 26(4A), 1993, pp. 29-31
We present a method of reconstruction of two-dimensional lattice defor
mation fields in crystals with periodically distorted near-surface reg
ions. The method is based on computer processing of triple-crystal x-r
ay diffractometry data. It has high spatial resolution (approximately
10(-2) mum) and sensitivity to lattice parameter variation of the orde
r of 10(-7). Deformation profiles in distorted Si crystals are reconst
ructed.
