We prepare CuCrO2 thin films with magnesium and nitrogen dopants. The solid state reaction method is employed to produce CuCrO2 targets with three different concentrations of Mg (0%, 2.5%, and 5%). The targets are used in an RF sputtering system to prepare thin films in the presence of N-2 as the reactive gas. In this manner, Mg and N atoms, respectively, replace Cr and O sites in the CuCrO2 structure and enhance the electrical and optical properties of the host material. This cationic-anionic substitution yields a superior hole transport and results in an increased conductivity of similar to 278 S cm(-1) which is considered as a record for p-type conductivity in transparent conducting doxides. Moreover, the co-doped CuCrO2 demonstrates a bandgap of 3.52 eV and a transmittance of about 69% in the visible region. Published by AIP Publishing.
