Abstract

This study investigated the effect of annealing on optical and electrical properties of MgS deposited by chemical bath deposition method onto glass substrates, the transmittance of the film was obtained from AVANTEX UV spectrophotometer in the wavelength range from 239.534 nm to 999.495 nm. Also, the electrical characteristics of the thin films were investigated using KEITHLEY four-point probe techniques. The films exhibit low reflectance, low absorbance and high transmittance in the visible region, the bandgap energy reduces from 2.4 eV before annealing to 2.2 eV after annealing. The resistivity decreases as annealing temperature increases. Therefore the MgS thin film can be used as a replacement for CdS which contains toxic element.
