- AlGaAs layers grown by molecular beam epitaxy on GaAs substrates were investigated before and after high hydrostatic pressure (1.2 GPa) at high temperature (770 K) treatment. In order to study the influence of high pressure - high temperature treatment on the physical properties of the AlGaAs layers, X-ray, electron transport and Raman scattering measurements were performed at room temperature. The observed changes in the lattice parameter, Raman spectra and free-carrier concentration were related to the strain relaxation and explained by the creation of misfit dislocations and other extended defects which were visible on the synchrotron X-ray topographs after high pressure - high temperature treatment.
