Effect of Oxygen Pressure on Thermoelectric Properties of p-Type CuAlO2 Films Fabricated by Pulsed Laser Deposition

We focus on the growth of p-type CuAlO2 thin films and its thermoelectric properties. Thin films are deposited by pulsed laser deposition technique on single-crystal sapphire substrates varying the oxygen partial pressure. Thin film deposited at oxygen partial pressure of 200 mTorr presents bigger g...
