Postgrowth annealing of plasma grown GaAs oxides in N2 and H2 result in very different electrical behaviors. By examining cross-sectioned specimens of these oxides with transmission electron microscopy, and correlating the observed structure with electrical measurements, it is demonstrated that metallic As at the oxide-semiconductor interface plays a significant role in determining the MOS characteristics.
