We show here that intrinsic hydrophobicity of HfO2 thin films can be easily tuned by the variation film thickness. used reactive high-power impulse magnetron sputtering for preparation high-quality with smooth topography and well-controlled Results a strong dependence wetting properties on thickness in range 50–250 nm due to dominance electrostatic Lifshitz-van der Waals component surface free energy. have found water droplet contact angle ranging from ≈120° 50 ≈100° 2300 nm. At same time...
In order to extend the life of boilers by applying an anti-corrosion coating without need dismantle them, it is advisable find coatings that can be applied using cheaper and portable techniques, such as Twin Wire Arc Spray technology (TWAS). this study, we compare selected NiCr-based two uncoated steel substrates (steel 1.7715 1.4903). Two coatings, Cr3C2 - 25% NiCr Hastelloy C-276 are deposited High velocity oxygen-fuel (HVOF) three NiCrTi, NiCrMo, Inconel 625, TWAS. addition corrosion...
Abstract The effect of deposition temperature on the structural and optical properties amorphous hydrogenated silicon (a-Si:H) thin films deposited by plasma-enhanced chemical vapour (PECVD) from silane diluted with hydrogen was under study. series at temperatures 50–200°C were inspected XRD, Raman spectroscopy UV Vis spectrophotometry. All samples found to be no presence crystalline phase. Ordered hydride regions proved XRD. measurement analysis substantiated results received XRD showing...
Abstract In this paper we report results from optical transmittance spectroscopy complemented with data on structure XRD measurements to determine properties of a series ZnTiO 3 perovskite thin films deposited glass by reactive magnetron co-sputtering. The members the differ titanium content that was revealed as an origin changes not only in but also dispersive properties. Low porosity has been discovered and calculated using Bruggeman effective medium approximation. An apparent blue-shift...
A study of the effect technology parameters (sputtering power, substrate temperature and post-deposition annealing) on structural, electrical optical properties aluminium-doped zinc oxide (AZO) thin films was carried out. The optimal preparation were found to get necessary AZO for application in solar cells - high figure merit (F ges 4 %/Omega), low sheet resistance (R <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">s</sub> les 10 Omega/square)...
RF diode sputtering of ZnO:Ga thin films by three types deposition at constant oblique-angle (80°) configuration is presented: simple oblique deposition, depositions substrate sequential turning around the normal - double an 180° angle and four-times 90°. XRD patterns azimuthal line profiles confirmed their inclined (002) texture SEM/TEM cross-section analyses indicated columnar crystallic structures: tilted about 11°, 2D- 3D- "pseudo-zigzag" ones. Both structure increased optical...
In this paper the possibility to form ultra-thin homogenous films doped by Ga (ZnO:Ga) continual or sequential sputtering is presented. An influence of post-deposition annealing on crystalline structure was studied. The ability create a highly consistent coverage (shell) three dimensional nanostructures (GaP nanowires) mode proven.
