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.
