摘要: Materials and structures for improving the performance of semiconductor devices include ZnBeO alloy materials, ZnCdOSe alloy materials, ZnBeO alloy materials that may contain Mg for lattice matching purposes, and BeO material. The atomic fraction x of Be in the ZnBeO alloy system, namely, Zn1-xBexO, can be varied to increase the energy band gap of ZnO to values larger than that of ZnO. The atomic fraction y of Cd and the atomic fraction z of Se in the ZnCdOSe alloy system, namely, Zn1-yCdyO1-zSez, can be varied to decrease the energy band gap of ZnO to values smaller than that of ZnO. Each alloy formed can be undoped, or p-type or n-type doped, by use of selected dopant elements.
