On the Structure of Thin 4 He Films on Solid Hydrogen
نویسنده
چکیده
We have investigated the adsorption of 4He onto a quench-condensed H2 film by means of surface state electrons. Oscillations in the surface state electron conductivity clearly reveal the layerwise character of the adsorption. At temperatures below 2K we have observed an anomaly in the conductivity around the completion of the first monolayer. This new feature is interpreted as an indication of a liquid-to-solid phase transition in the first layer.

Thermal Oxidation Times Effect on Structural and Morphological Properties of Molybdenum Oxide Thin Films Grown on Quartz Substrates
Molybdenum oxide (α-MoO)thin films were prepared on quartz and silicon substrates by thermal oxidation of Mo thin films deposited using DC magnetron sputtering method. The influence of thermal oxidation times ranging from 60-240 min on the structural and morphological properties of the preparedfilms was investigated using X-ray diffraction, Atomic force microscopy and Fourier transform infrared...
متن کاملNano-structural Characterization of Post-annealed ZnO Thin Films by X-ray Diffraction and Field Emission Scanning Electron Microscopy
ZnO thin films were deposited on Si(400) substrates by e-beam evaporation technique, and then post-annealed at different annealing temperatures (200-800°C). Dependence of the crystallographic structure, nano-strain, chemical composition and surface physical Morphology of these layers on annealing temperature were studied. The crystallographic structure of films was studied using X-Ray Diffracti...

In this paper, a modified sol-gel method using peroxotitanic acid sol (PTA) was applied for the preparation of TiO2 nanostructured thin films on glass plates. The peroxotitanic acid sol was synthesized using titanium isopropoxide, isopropylalchol, H2O and hydrogen peroxide. TiO2 films were then calcined at 500oC and characterized by X-ray diffraction ...
