Calculation of time-dependent flows of sputtered material in the asymmetric alternating current glow discharge
, , , Vacuum 2007 Vol. 81 No. 6 P. 771-773
Diffusion transport of material sputtered from the surface of the powered electrode in the asymmetric alternating current discharge is theoretically studied. It is shown that amplitudes of the non-stationary component of the sputtered atom (SA) flow densities at the electrodes depend on the discharge frequency and two dimensionless parameters, which are functions of the SA ...

At ultra-low temperatures, the transport properties of two types of quasi-one-dimensional superconducting microstructures were studied: thin channels tightly packed in the form of a meander, and chains of superconductor-insulator-superconductor tunnel contacts. Both types of microstructures demonstrated high values of high-frequency impedance and / or dynamic resistance. The study opens up the possibility of using such ...

Hydrogen can be inserted into Si(100)-2 × 1-H during surface preparation or during the hydrogen desorption lithography used to create atomic-scale devices. Here, a hydrogen atom inserted into a hydrogen monolayer on the Si(100)-2 × 1 surface has been studied using density functional theory.

В работе исследовалась магнетопроводимость тонких пленок Bi2Se3 с защитным слоем Se, выра щенных на подложках (111) BaF2. Наблюдаемая отрицательная магнетопроводимость в малых полях, обусловленная эффектом слабой антилокализации, так же как и осцилляции Шубникова–де Гааза в больших полях, определяется только перпендикулярной к плоскости пленки компонентой магнитного поля. Полученные экспериментальные результаты могут быть разумно объяснены в предположении на личия в исследуемых пленках ...

The epitaxial growth of tellurium films by chemical vapor deposition is investigated. It is established that, under thermochemical activation conditions, tellurium films grow from vapor phase in the (10 $$\bar 1$$0) plane, parallel to the (001) muscovite substrate and the (0001) sapphire substrate. It is demonstrated that tellurium films on (001) muscovite substrates are more ...

Single crystals and films of 2-methylbenzimidazole were obtained by evaporation from an alcohol solution. Films are a texture with a predominant orientation of the pseudo-tetragonal axis in the film plane. The blocks are split spherulite-type crystals in which the pseudotetragonal axis rotates around the center of the block. Dielectric hysteresis loops in the temperature range ...

We insert and manipulate a single chlorine atom in chlorine monolayer on a Si(100)-2 × 1 surface using a scanning tunneling microscope. Two objects were created—a Cl atom in a groove between two dimer rows, and bridge-bonded Cl on a silicon dimer. Changing the voltage polarity leads to conversion of the objects into each other. ...

We obtain that at frequencies lower than Fermi energy the metallic response in a BDS film manifests in the existence of surface-plasmon polaritons, but at higher frequencies the dielectric response is dominated and it occurs ...
