Synthesis and characterization of chemically deposited nickel substituted CdSe thin film

[Display omitted] ▶ Cd 0.5Ni 0.5Se thin film. ▶ Chemical bath deposition method. ▶ Characterization techniques like XRD, SEM, optical studies and electrical properties. ▶ Semiconducting material. The technologically important Cd 0.5Ni 0.5Se thin film has been developed by solution growth technique on non-conducting glass substrate in tartarate bath containing Cd +2, Ni +2 ions and sodium selenosulphate in an aqueous alkaline medium at room temperature. Various preparative conditions of the thin films are outlined. The films were characterized by X-ray diffraction, scanning electron microscope, optical absorption and electrical measurements. The X-ray diffraction study indicates that the film is polycrystalline in nature with hexagonal phase. Scanning electron micrograph shows that the film is homogeneous with well-defined grains. The films have high optical absorption coefficient. Thermoelectric power measurement shows p-type conduction mechanism.
