Highly conductive and transparent magnesium-doped cadmium oxide (CdO:Mg) thin films have been deposited on suitably cleaned glass substrates maintained at 375 degrees C by spray pyrolysis technique using perfume atomizer. The magnesium content in the films is varied from 0 to 8 at% in steps of 2 at%. The effect of Mg doping on the structural, morphological, optical and electrical properties of the Cdo thin films has been studied. All the films exhibited cubic structure with a preferential orientation along the (1 1 1) plane irrespective of the Mg doping level. SEM analysis showed that the film morphology modifies from spherical shaped grains to closely packed cauliflower shaped nanostructures with Mg doping. Except for the film coated with 2 at% Mg dopant, all the other doped films exhibited a blue shift in the optical band gap. Electrical studies revealed that the CdO:Mg film coated with 8 at% Mg dopant had a minimum resistivity of 0.0853 x 10(1) Omega-cm. (C) 2015 The Authors. Published by Elsevier GmbH.
