Abstract

The rule of the electrical and solid state properties of sulphide based thin film has made it interesting for us to carry out a study on the electrical and solid-state properties of aluminum doped NiS deposited by chemical bath deposition method has been carried out in this work in order to ascertain the influence of the   concentration of aluminum as a dopant on the electrical and solid state properties of NiS thin film material as pointed out. And from the results, it was obviously seen as showcased from the results such as the index of refraction, extinction coefficient, dielectric constants, optical conductance that there were significant influence of Al on the trends of these properties, in particular the electrical properties as obtained using four point probe  that  they were  variations in trend of the graphs  as  the concentration of  dopant, aluminum were varied  indicating its  effect on  the behavior of the aforementioned properties  of the thin film in question thereby clarifying the belief that  generally doping is one of the parameters that can  be used to modify the sulphide based chalcogenide.
