Abstract
ZnSe bilayer thin films of thickness 343 Å were deposited onto soda-lime glass substrates by thermal vacuum evaporation technique using NANO 36 thermal evaporator, under vacuum pressure of 2.9 1 x10-5 torr. The optical characteristics of the film were done by using AVANTEX UV spectrophotometer in the wavelength range from 239.534 nm to 999.495 nm. The surface morphology studies were also observed by ASPEX 2030 Scanning Electron Microscopy (SEM) operated at accelerating 16 KV potential. Also the electrical characteristics of the thin films were investigated using a KEITHLEY four-point probe technique. The investigation of the optical properties of the thin films as deposited and annealed at different temperatures showed high transmission in the NIR region with good absorption in the visible and UV region. The extrapolated band gap energies were high between 3.60 eV and 4.15 eV and electrical resistivities were low between 0.475 Ωm and 9.070 Ωm.
