  • Electronic semiconductor device based on copper nickel and gallium-tin-zinc-copper-titanium p and n-type oxides, their applications and corresponding manufacture process
    Patent number: 8274082
    Abstract: The present invention corresponds to the use of p and n-type oxide semiconductors based on copper nickel (OCuxNiy, with 0<x<3; 0<y<3) or multicomponent Gallium-Tin-Zinc-Copper-Titanium oxide, designated here after as GSZTCO, in different molar compositions, having an amorphous or crystalline structure and with the electrical characteristics of a donor or electron acceptor semiconductor, doped or not doped with impurities, such as, Zirconium or nickel or nitrogen, as a way to control the semiconductor electronic behaviour (valence); including the manufacture process at room temperature or temperatures below 100° C.
