Abstract
ZnO and ZnO:Cr films were grown by the chemical spray deposition (CSD). The effect of the Cr content on ZnO was studied. All ZnO films show polycrystalline, hexagonal wurtzite structure, with (002) dominant plane. AFM displayed that films have a compact surface, its root mean square roughness increased with Cr percentage. The average diameter was smaller than 64 nm. The optical bandgap was evaluated using Transmittance data. Their values were found to be decreases via increment in Cr doping.
