E. Zolotoyabko et al., THE ULTRASOUND-INDUCED NARROWING EFFECT OF ROCKING CURVES IN STRAINEDSILICON-CRYSTALS, Acta crystallographica. Section A, Foundations of crystallography, 50, 1994, pp. 253-257
Surface acoustic waves were combined with double-crystal X-ray diffrac
tometry in order to study strained silicon crystals. A narrowing effec
t in the rocking curves was observed owing to the ultrasound-induced m
odification of the X-ray trajectories. It is shown that the narrowing
effect is strongly related to the lattice strain and can be used to in
crease the strain sensitivity of the X-ray diffraction technique.
