Abstract
It is shown that nickel oxide deposited on GaAs insures rapid growth of oxide layers at low oxidation temperatures, inhibits the degradation of the substrate surface, and contributes to the binding of the volatile component with the formation of As2O3, As2O5, and nickel arsenates. A reaction scheme for the thermal oxidation of NiO(40 and 25 nm)/GaAs heterostructures is proposed which takes into account reactions at the oxide-semiconductor interface.
