α-Silicene as oxidation-resistant ultra-thin coating material

α-Silicene as oxidation-resistant ultra-thin coating material

By performing density functional theory (DFT)-based calculations, the performance of α-silicene as oxidation-resistant coating on Ag(111) surface is investigated. First of all, it is shown that the Ag(111) surface is quite reactive against O atoms and O2 molecules. It is known that when single-layer silicene is formed on the Ag(111) surface, the 3 × 3-reconstructed phase, α-silicene, is the gro...

Ultra-Thin Pyrocarbon Films as a Versatile Coating Material

The properties and synthesis procedures of the nanometrically thin pyrolyzed photoresist films (PPF) and the pyrolytic carbon films (PCF) were compared, and a number of similarities were found. Closer examination showed that the optical properties of these films are almost identical; however, the DC resistance of PPF is about three times higher than that of PCF. Moreover, we observed that the w...

Ultra-thin aluminum oxide as a thermal oxidation barrier on metal films

We have investigated the role of aluminum oxide films as barriers to thermal oxidation of Co, Ni, Fe, Ni Fe , Mn, Ta, Cu 80 20 and Cr in air. The oxidation of the film is monitored by measuring the electrical resistance following a brief anneal in air. We find that 0.3 and 1 nm Al protect the underlying metal film against thermal oxidation in air at temperatures of a few hundred degrees above t...
