研究紹介
In our lab, we focus on delafossite ceramics. Delafossite CuGaO2 as a p-type semiconductor is classified as a wide band-gap semiconductor owing to direct transitions on the high energy side. Solid state reaction and sol-gel synthesis are applicable as traditional methods for synthesizing delafossite CuGaO2. However, both synthesis methods require high temperatures, and the sol-gel method additionally requires a nitrogen gas atmosphere. In this study, hexagonal-platelet CuGaO2 is synthesized using a hydrothermal method, which can be applied to the synthesis of the CuGaO2/ZnO hybrids. As a result, it was found that the surface of platelet CuGaO2 particles could be used to create hybrids with n-type ZnO semiconductors.
