Abstract

CdGa2O4 spinel was found to be a promising material as a transparent electronic conductor. By measurements of diffuse reflectance spectra, CdGa2O4 was found to have a wider band gap (∼3.5 eV) than indium tin oxide. The electrical conductivity of the sintered sample of CdGa2O4 was over 102 S cm -1 with no intentional doping.
