Speech Title: Epitaxial Growth of Gallium Oxides and Solar Blind Ultraviolet Photodetectors

Abstract: Gallium oxide, as a new type of wide bandgap semiconductor materials, with many excellent physical properties (such as: the wide bandgap, ~ 4.9 eV, the large breakdown electric field, ~ 8 MV/cm), exhibits the wide application prospect in devices. In recent years, especially since the high quality 2 inch of gallium oxide single crystals were obtained, gallium oxide materials have attracted intensive attentions by researchers from all over the world. In this talk, I will briefly review the progress in materials and devices of gallium oxide, and then focus the epitaxial growth of gallium oxides and solar blind ultraviolet photodetectors.
