Abstract: GaAs was used as the target material for the deposition of GaN films by reactive sputtering. The films were grown at different compositions of the sputtering gas mixture (0-100% nitrogen in argon) at substrate temperatures of 450 and 550 degrees C. The films were studied using XRD and XPS techniques. Even a small quantity of nitrogen in the sputtering medium was found to prevent the formation of GaAs on the substrate. Films grown at 550 degrees C using 100% nitrogen as the sputtering-reactive gas were found to be single phase (0002) oriented hexagonal gallium nitride and revealed complete absence of arsenic.
