摘要

ZnS/MnS super lattice thin films were grown on glass substrates by Chemical Bath Deposition technique. Equimolar aqueous solutions of ZnCl_2:thiourea and MnCl_2·2H_2O:thiourea were taken separately. The substrates were placed vertically in the beakers containing the precursor described above, and the films are deposited at 85?C for an hour. The as deposited films are annealed at 200?C for about two hours. X-ray diffractometry method was used to obtain structural characterization. The UV-vis absorption spectrometry was employed to find the optical properties. The refractive-index, dielectric constant, optical conductivity, electrical conductivity and extinction coefficient were determined by various equations based on the data. The valence band and conduction band offset voltages for ZnS/MnS were determined as 0.7 eV and 0.1 eV respectively and for MnS/ZnS were 0.4 eV and 0.3 eV respectively. The band alignment of both superlattice was found to be as Type I.
