Thin films of cadmium oxide (CdO) were grown on borosil glass substrates by successive ionic layer adsorption and reaction method. The films were found to be amorphous. The thickness of the films increased with deposition cycles and concentration of the source solutions. Bandgap of the films were found to decrease from 2.7 eV to 2.5 eV as the thickness of the films increased. The films had almost stoichiometric composition. The films were found to form ohmic contacts with aluminium and showed a resisitivity of 0.47 ohm-cm.
