Improvement of Morphological, Optical, and Electrical Properties of Nickel-Coated CdS Prepared by Thermal Deposition Method

Abstract

Pure and CdsNi(NP) were prepared by thermal deposition. The influence of the Ni doping ratio has studied these films' structural, morphological, optical, and electrical properties. Polycrystalline hexagonal (CdS and CdSNi) were shown to have [101] preferential orientation by XRD analysis. Images from the (FE-SEM) showed low-dimension NP formation, and the NP size was in the region of 15–25 nm. Optical analysis has shown that all the films are really transparent. In the visible region, the transmittance ranges between 75% and 80%, were based on the concentration of the dopant. The film with a Ni ratio of 0.3 % showed a minimum resistivity of 6.14x105 Ω.cm at RT.
