摘要
Oxide semiconductor alloys of x(LiGaO(2))(1/2)-(1-x)ZnO were synthesized by a standard solid state reaction. The wurtzite-type single phases were obtained in the wide composition range of x <= 0.38 because the beta-LiGaO(2) possesses a wurtzite-derived structure and approximately the same lattice constants with ZnO. The resulting alloys showed characteristics of wide band gap oxide n-type semiconductor; the optical transparency reached over to the ultraviolet (UV) light. The electrical conductivity and energy band gap for 0.38(LiGaO(2))(1/2)-0.62ZnO were 8.2 Omega(-1) cm(-1) and 3.7 eV, respectively, at room temperature. The alloy is a good candidate for the barrier material of the ZnO-based heterostructures and UV-transparent electrodes. (C) 2008 American Institute of Physics.
