Popis: A technique of pulsed Ruby laser induced liquid-solid interface reaction is employed to induce controlled and selective oxide growth on GaAs (111). Small-angle and bulk XRD spectra have been recorded at different stages of processing for investigations of the structural states near the surface and the interface regions. The changes in the surface electronic structure due to oxide growth are characterized by analysing Ga(3d) and As (3d) XPS spectra. Results are reported for the dependence of oxidation on the energy density of the incident laser beam and the number of pulses.
