Abstract

ZnGa₂O₄ having the spinel structure was prepared, and optical and electrical properties of the material were measured. By the measurements of diffuse reflectance spectra, ZnGa₂O₄ was found to have a wider band gap (∼5 eV) than ITO (indium tin oxide). Electrical conductivity of the H₂-annealed ceramic of ZnGa ₂O₄ was 3×10¹ S cm^-1. Thus the ZnGa₂O₄ spinel was found to be a new UV-transparent electronic conductor.
