    摘要: An electro-conductive ultraviolet light transmitting Ga.sub.2 O.sub.3 material (10) with a metallic oxide phase is deposited on a GaAs substrate or supporting structure (12). The Ga.sub.2 O.sub.3 material or thin layer comprises a minor component of metallic IrO.sub.2. The Ga.sub.2 O.sub.3 thin layer may be positioned using thermal evaporation (106) of Ga.sub.2 O.sub.3 or of a Ga.sub.2 O.sub.3 containing a compound from an Iridium crucible (108). Alternatively, the Ir may be co-evaporated (110) by electron beam evaporation. The electro-conductive ultraviolet light transmitting material Ga.sub.2 O.sub.3 with a metallic oxide phase is suitable for use on solar cells and in laser lithography.

    摘要: An insulator-compound semiconductor interface structure is disclosed including compound semiconductor material with a spacer layer of semiconductor material having a bandgap which is wider than the bandgap of the compound semiconductor material positioned on a surface of the compound semiconductor material and an insulating layer positioned on the spacer layer. Minimum and maximum thicknesses of the spacer layer are determined by the penetration of the carrier wave function into the spacer layer and by the desired device performance. In a specific embodiment, the interface structure is formed in a multi-wafer epitaxial production system including a transfer and load module with a III-V growth chamber attached and an insulator chamber attached.
