Abstract
The wetβoxidation effect on optical and electrical properties of CuAlO~2~ thin films was investigated with different water vapor pressures. Preferential (006) oriented films were obβtained after wetβoxidation. The transmittance was 50β85% for the visible range and the optical band gap was estimated to be 3.96β4.20 eV. The pβtype nature of the films was confirmed by Hall effect measurements. The resistivity and transmittance were increased as water vapor pressure, and these phenomena were caused by the decrease of lower oxides with higher oxygen pressure.
