    Gold/palladium (Au/Pd) Bimetallic Thin Film Deposition by Radio Frequency Magnetron Sputtering Technique
    (2019) Şenay, Volkan
    In this study, two gold/palladium (Au/Pd) thin films having 20 nm and 80 nm thicknessvalues were simultaneously deposited on glass substrates by adjusting target-substrate distance viaradio frequency (RF) magnetron sputtering technique. The optical and surface properties of theproduced thin films were investigated by using UV-VIS spectrophotometer, interferometer,tensiometer and atomic force microscope. The effects of film thickness on the investigated propertiesof the thin films were reported.

    Optical and Surface Properties of Nanostructured ZnO Semiconductor Thin Films Synthesized by RF Magnetron Sputtering
    (2019) Şenay, Volkan
    In this research, ZnO thin films were deposited on glass microscope slides in three separate experiments with RF inputpowers of 50 W, 100 W and 125 W by means of RF magnetron sputtering technique. Each deposition process wasconducted for 30 minutes. Spectroscopic reflectometer, UV-VIS spectrophotometer and atomic force microscope(AFM) were used to examine the effect of sputtering power on the optical and surface properties of the produced thinfilms. The level of reflectivity and transparency, refractive index and band gap energy values as well as surfacehomogeneity and roughness were observed to rely on the RF input power. The optical band gap energy values wereabout 3.83-3.87 eV. The produced highly transparent ZnO thin films can be used in various optoelectronic devices andfuture transparent conductive electrode implementations.
