Theoretical and Experimental Investigation of Optical Properties of ZnS Zig-Zag Thin Films

Zigzag ZnS thin 􀀕lms prepared by the thermal evaporation method using glancing angle deposition (GLAD) technique. ZnS 􀀕lms with the zigzag structure were produced at deposition angles of 0˚, 70˚ and 80˚ at room temperature on glass substrates. Surface morphology of the 􀀕lms was characterized by using 􀀕eld emission scanning electron microscopy (FESEM). The optical properties of the specimens were investigated by using UVVis spectroscopy technique. To characterize the porosity of the simulated structures, the PoreSTAT software which analyses the NASCAM software was employed. The optical transmissions of the samples were calculated by using NASCAM optics package. The simulation results are completely in agreement with the experimental results
