Abstract

Recent results suggest that CuAlO₂ may be a p-type transparent conductor, but thin film synthesis is difficult because of the complex Cu:Al:O phase diagram. We report a robust method of making c-axis oriented CuAlO₂ thin films. Thin film precursors of CuAlO₂ were deposited on sapphire (001) substrates by radio-frequency sputtering and by pulsed-laser deposition. Subsequent annealing in air at 1050 °C in a closed crucible containing Al₂O₃ and CuO powders yielded nearly phase-pure, biaxially textured CuAlO₂. The films were p-type and transparent with a gap of 3.5 eV.
