Abstract

It was demonstrated that the MgIn₂O₄ spinel is a very promising material as a transparent electronic conductor. By the measurements of diffuse reflectance spectra, the optical band gap of MgIn₂O₄ (∼3.4 eV) was found to be wider than that of ITO (indium tin oxide). Electrical conductivity of the sintered sample of MgIn₂O₄ at room temperature has reached almost 10² S cm⁻¹ with no intentional doping. The conduction was found to be due to electrons introduced from oxygen vacancies.
