Ar&H2 plasma treatment was proposed to enhance the response of a p-CuAlO2 sensor toward volatile organic compounds. Comprehensive defect characterization studies indicate a substantial increase of surface unsaturated oxygen vacancy (VO) defects via plasma treatment, which could provide active sites for molecule adsorption and the subsequent interfacial redox reaction.
