Properties of a Novel Amorphous Transparent Conductive Oxide, InGaO3(ZnO)m

Abstract

Novel amorphous transparent conductive oxides, InGaO3(ZnO)m, where m is an integer less than four, was developed. Optical transmittance in the visible region exceeded over 80 % and the electric conductivity at 300 K was as large as 400 S/cm. Both Seebeck and Hall coefficients exhibited negative values, indicating the conduction was n-type. It was suggested that 4s orbital of Zn2+ played a significant role for the formation of the extended state responsible for the conduction, while In3+ acted as a modifier for the stabilization of amorphous state.
