Abstract
This novel research centered on synthesizing NiTe film through electrochemical deposition technique. The film was doped with molybdenum at varying molar concentrations of 0.1, 0.2, and 0.3 M. The structure, morphology, elemental, optical, and electrical characteristics of the prepared samples with preferential orientation in the (1 0 0) plane have been investigated. Hexagonal crystal structure with prominent peaks was gotten from the X-ray diffractograms. The surface morphologies showed dense micrograins with high optical absorption while the basic elemental compositions of the deposited films were confirmed from the EDX plots. Optical plots gave maximum absorbance values at the ultraviolet region and reduced reflectance values at increasing molar concentrations. The band gap energy values ranging from 2.01 to 1.68 eV decreased at increasing molar concentrations. The electrical results gave improved electrical conductivity as the dopant concentration increased. The prepared samples find useful application in optical and solar cell devices.
