Abstract
The homologous compounds In1-xGa1+xO3(ZnO)k (where k = 1, 2, or 3) were prepared at a temperature of 1400 °C. The solubility limits (as determined via X-ray diffractometry) were 0.473+ content increased and k decreased. The conductivity increased as k decreased and the In3+ content increased. A maximum conductivity of 250 S/cm was obtained for k = 3 and [In]/([In]+[Ga]) = 1 after reduction. The minimum absorption edge of 325 nm was obtained for k = 2 and [In]/([In]+[Ga]) = 0.35 prior to reduction. The potential for metastable phases in the In-Ga-Zn-O system with enhanced transparent-conducting properties has been discussed.
