Structural and electrical properties of copper doped In₂O₃ nanostructures prepared by citrate gel processes

Copper doped indium oxide (In2−xCuxO3) nanostructures were prepared by a simple citrate gel process using indium nitrate and copper nitrate as precursors. The influence of the dopant concentration (x = 0, 0.03, 0.05 and 0.07) on the structural, morphological and the electrical properties of indium oxide was studied. The crystallite size and the surface roughness (root mean square roughness and the mean roughness) of the prepared samples...
