In this work we report about the template-confined dewetting of Au nanoscale film on SiC substrate in view of a surface patterning control. In this approach, the Au surface pattern order, on the SiC substrate, is established by a template confined deposition on a micrometric scale. Then, a film dewetting process is induced by thermal processes. Using scanning electron microscopy analyses, we studied...
Niobium carbide thin films have been deposited on Si(100) substrates by direct current reactive magnetron sputtering using CH 4 as a carbon source. With increasing FCH4 from 4 to 22 sccm, the carbon content for the film increases from 32.7 to 68.7 at.% gradually, accompanying with a phase transition from hexagonal-Nb 2 C to cubic-NbC, and at the highest carbon content, the film exhibits...
Ni films with a thickness of 45–240 nm were sputter-deposited on HCl-doped polyaniline (HCl-PANI) substrates at 300 K, forming the Ni/HCl-PANI composites. All the Ni films grow with columnar grains. The grain size increases with increasing film thickness. A temperature dependence of the resistance within 5–300 K reveals that all the Ni/HCl-PANI composites exhibit a metal–semiconductor transition....
Back reflectors based on Aluminum and Molybdenum as the reflecting materials and ZnO:Al as the transparent conductive oxide, were deposited at low temperature on polyethylene naphthalate by magnetron sputtering. The optimization of the layer thickness of the constituent materials and the final texture of the structure was performed in order to achieve structures with appropriate properties to be applied...
Energetic Au ion sputtering of crystalline Ge surface at normal incidence and room temperature can produce nanodot morphology, which has been studied by atomic force microscopy. The cross-sectional transmission electron microscopy of the dot structure reveals that the implanted Au does not form solid solution with Ge, but preferentially segregates at the top edges of the dots as well as near the amorphous/crystalline...
