We investigated the spectral-dependent dielectric function and temperature-dependent bandgap energy of layered chalcogenide FeIn2Se4 crystals. The critical-point energy and Lorentzian broadening were analyzed by fitting second-derivative spectra usin

Ratio of two peaks in X-ray induced vanadium L3M23M45 Auger electron spectra has been used to monitor oxidation state of V2O3 thin film surface followed by vacuum annealing. The V2O3 film was grown with sol-gel method on the Al2O3 (0001) substrate. T

Fe 2 SiO 4 thin films have been grown on n-type, p-type and semi-insulating Si(100) substrates by molecular beam epitaxy. When Fe-O thin films were deposited on Si(100) substrate at 300 °C, the film reacted with Si, resulting in a Fe 2 SiO 4 film be

Strain effects in epitaxial films can substantially enhance individual functional properties or induce properties which do not exist in corresponding bulk materials. The bcc α-Fe50Mn50 films are a ferromagnetic with a Curie temperature between 650 K

We investigated the magnetic field-dependent Hall effect and the thermopower in VO 2 thin films at various temperatures by using physical property measurement systems. From the ordinary Hall effect measured at 300–370 K, it was found that the Hall

In recent years, many engine manufacturers have turned to downsizing and boosting of gasoline engines in order to meet the ever more stringent fuel economy and emissions regulations. With an increase in the number of turbocharged gasoline engines, so

Many researchers have produced various results for the mechanism of the metal-insulator transition (MIT) of VO 2 . This seems to be because of the influence of various VO x phases in the sample thin-film. VO x has many phases, and VO 2 is in only a s
