Popis: Single phase p-type CuAlO 2 thin films were synthesized through the chemical solution deposition method. The effects of post annealing temperature on the micro-structural, morphological and electrical properties have been studied. Via the optimized annealing treatment, the Hall effect measurements indicate that the CuAlO 2 film belongs to the p-type semiconductor with intrinsic hole carriers of 6.71 × 10 16 cm − 3 . The optical direct bandgap of the CuAlO 2 film was estimated to be 3.48 eV by room temperature photoluminescence measurement, while the transmittance in the visible region was as high as 70%.
