Abstract

Considering CuCrO2 to be a promising p-type transparent conducting oxide, unprecedented simultaneous cationic–anionic doping is carried out to achieve superior hole transport while maintaining its transparency. Magnesium and sulphur are doped at Cr and O-sites respectively by solid-state approach (CuCr1−xMgxO1−ySy, x, y ranging 0–5 atomic %) with significant doping confirmed by Rietveld refinement. UV–Vis spectroscopy is observed to imply promising optical properties of engineered materials. DC conductivity of co-doped CuCr0.95Mg0.05O1.9S0.1 is observed to be twice as large compared to CuCr0.95Mg0.05O2 at 300 K, which is consistent with the lower frequency shift of the negative differential susceptance () and the admittance peak, indicating higher ‘metallicity’ upon co-doping. Hole mobility of 16.26 cm2 V−1 s−1 at 300 K is observed for the co-doped CuCrO2. This strategy combines an established doping scheme at the cationic site with our newly developed anionic chalcogen doping, aiming to overcome a long-standing transport bottleneck in the field of semiconductor oxides.
