  • P-type oxide semiconductor and method for manufacturing same
    Patent number: 11916103
    Abstract: A new and useful p-type oxide semiconductor with a wide band gap and an enhanced electrical conductivity and the method of manufacturing the p-type oxide semiconductor are provided. A method of manufacturing a p-type oxide semiconductor including: generating atomized droplets by atomizing a raw material solution containing at least a d-block metal in the periodic table and a metal of Group 13 of the periodic table; carrying the atomized droplets onto a surface of a base by using a carrier gas; causing a thermal reaction of the atomized droplets adjacent to the surface of the base under an atmosphere of oxygen to form the p-type oxide semiconductor on the base.
    Type: Grant
