β¦ Synopsis
Multi-crystal X-ray diffraction has been used to study the strain located close to the Si-SiO 2 interface of device grade SIMOX substrates. It is found that the strain is located within a layer whose thickness is about 15% of the silicon overlayer. The quality of this layer can be restored by annealing at 1000 Β°C.

InGaAs/InP multi-quantum well structures, grown by metal-organic vapour phase-epitaxy, were investigated by Raman spectroscopy and X-ray diffractometry to analyse the influence of precursor gas switching parameters on the interface abruptness. Owing to carry-over effects, InAsP is formed at the InGa
