Chemical deposition of polycrystalline ZnSe thin films from Malonic acid solution: Nucleation and growth mechanism, structural, optical and electrical studies

Abstract :
Zinc selenide (ZnSe) polycrystalline semiconductor thin films have been synthesized by dip method in malonic acid solution. The formation of nucleus and growth process of this technique has been studied. The XRD pattern shows a characteristic cubic structure with a (111) crystallographic preferred orientation. SEM studies reveal that grains are uniformly dispersed on the surface of the substrates. The optical energy gap was found to be 2.80 eV. The activation energies are 0.053 and 0.317 eV for low and high temperature region, respectively obtained from electrical measurement.
