详细
Complex oxide films with a thickness of about 200 nm are formed during the thermal oxidation of GaAs with magnetron-deposited V2O5 and MnO2 nanolayers. The electrical parameters of the films (reverse-bias breakdown voltage and current density) are determined by the method of current–voltage (I–V) characteristics at room temperature in the bias range from –5 to +5 V, and their composition and surface morphology are investigated. It is shown that V2O5 facilitates the more intense (in comparison with MnO2) chemical bonding of arsenic at the internal interface with the formation of As2O5. As a result, thermally oxidized V2O5/GaAs heterostructures exhibit higher breakdown voltages.
