A CuAlO2 (CAO) p-type thin film transistor (TFT) is demonstrated. CAO with dominance phase along the (004) plane was prepared by digitally processed DC sputtering (DPDS) under a layer-by-layer (LBL) approach. The fabricated CAO p-TFT exhibits field effect mobility of 4.24 cm2V-1s-1 (that is the highest to our knowledge). The novel approach (i.e., DPDS-assisted LBL) for a controlled stacking deposition is found to be a good route in the growth of CAO thin film.
