Highly conducting and transparent aluminum doped CdO thin films were deposited using pulsed laser deposition technique. The effect of growth temperature on structural, electrical, and optical properties was studied. It is observed that the film orientation changes from preferred (1 1 1) plane to (200) plane with increase in growth temperature. The electrical resistivity of the films was found to increase with increase in growth temperature. The low resistivity of 4.3 x 10 (5) Omega cm and high transparency (similar to 85%) was obtained for the film grown at 150 degrees C. The band gap of the films varies from 2.74 eV to 2.84 eV.
