Abstract
To provide a gallium oxide-based semiconductor with its bandgap being sufficiently reduced, and a manufacturing method thereof. A gallium oxide-based semiconductor containing a mixed crystal having a composition represented by (GaFe)O, wherein 0.10≤x≤0.40 and 0.85≤y≤1.2, wherein the mixed crystal has a beta-gallia structure, is provided. Also, a method for manufacturing the gallium oxide-based semiconductor, including depositing a mixed crystal having a composition represented by (GaFe)O, wherein 0.10≤x≤0.40 and 0.85≤y≤1.2 on a substrate surface by a pulsed laser deposition method, wherein denoting the temperature of the substrate as T° C., x and T satisfy the relationship represented by 500x+800≤T<1,000, is provided.
