| Research Abstract |
Ga2O3 related materials, which are relatively novel wide-band-gap semiconductors, were studied in this research. Especially, we focused on the most stable ・-phase. As for electrical application, we have succeeded control of conductivity and band-gap engineering. Photocatalytic activities of Ga2O3 were also investigated in detail for optical application. We also demonstrated epitaxial stabilization of meta-stable phases of ・and ・. Furthermore, we have achieved ZnGa2O4 single crystalline film with a single domain and characterized its physical properties.
