  • Patent number: 12297527
    Abstract: A method for preparing a p-type gallium oxide film is provided. An MxGa1-xN target material is subjected to ablating, sputtering or evaporation in a vacuum chamber via physical vapor deposition to obtain MxGa1-xN clusters, where M is selected from the group consisting of Al, Sc, In, Y and Lu, and 0<x<1. The MxGa1-xN clusters are oxidized by O2 to obtain M-N co-doped p-type gallium oxide film on a substrate. The MxGa1-xN target material is prepared from MN powder and GaN powder through ball milling, pressing and sintering. A p-type gallium oxide film prepared by the method, and its application in the manufacturing of solar-blind ultraviolet detection devices and high-power electronic devices are also provided.
