Yttria-stabilized zirconia (YSZ) thin films were deposited successfully using RF magnetron sputtering. The substrate had been used are sapphire glass. A pure ceramic of Zr-Y is synthesized and processed into a planar magnetron target which is reactively sputtered with an Argon-Oxygen gas mixture to form Zr-Y-O nanostructure. The aim of this research is to study the conductivity and roughness YSZ thin film by using RF magnetron sputtering by varying the temperature deposition parameter. By lowering the YSZ thin film into nanostructure would enable for SOFC to be operate at lower temperature below 400°C. The YSZ nanostructure were controlled by varying the deposition parameters, including the deposition temperature and the substrate used. The crystalline of YSZ structure at 100W and temperature 300°C. The surface morphology of the films proved that at 300°C temperature rate deposition showed optimum growth morphology and density of YSZ thin films. Besides, the high deposition subtrate temperature affected the thickness of YSZ thin film at 80nm by using surface profiler. A higher rate of deposition is achievable when the sputtering mode of the Zr-Y target is metallic as opposed to oxide. YSZ is synthesizing to obtain the optimum thin film for SOFC application.

AbstractThin films of collagen were prepared by pulsed laser deposition (PLD) at room temperature on Si substrates using a KrF laser (248 nm) over a fluence range from 0.2–1.5 Jcm-2. The effects on film composition and morphology of ambient gas (Ar, Ar/H2O vapor), quenching atmosphere (Ar, Ar/H2O vapor), and fluence were examined. Fourier transform infrared spectroscopy (FT- IR) demonstrated that, independent of deposition parameter, the PLD films contained the characteristic Amide I and II functionalities of the collagen target and indicated that the secondary structure was altered by the PLD process. The surface morphology of the films was a function of the laser fluence and the gas environment during either film deposition or quenching at the end of deposition. Preliminary gel electrophoresis examination of deposited films suggested the collagen had not maintained the triple helical structure of the native collagen. X-Ray diffraction (XRD) indicated that all of the films, deposited under any conditions, were predominantly amorphous.
