The elemental and chemical compositions throughout the thickness of the GaAs native oxide layer slightly irradiated by Ar+ ions have been studied by synchrotron-based photoelectron spectroscopy at different photon energies enabling variation of probing depth. The presence of only two phases was observed: of the gallium oxide Ga2O3 and elementary arsenic Aso generated due to complete decay of arsenic oxides under the ion irradiation. Depth composition profiles were determined nondestructively. Despite inhomogeneous depth distribution, these profiles demonstrated domination (90 at %) of the dielectric Ga2O3 phase virtually throughout all the oxide thickness (~2 nm).
