The charge state change of MOS structures with multilayer dielectric films SiO2–PSG under highfield injection modification at different temperatures is studied in this article. The effect of temperature on the thermal stability of the negative charge component used to adjust the threshold voltage of MOS transistors is investigated. It is found that the performance of the highfield injection modification of MOS structures in the mode of constant current at elevated temperatures increases not only the density of the trapped negative charge but also its thermally stable component.

In this paper, we present our approaches to the development of fiber-coupled superconducting single photon detectors with enhanced photon absorption. For such devices we have measured detection efficiency in wavelength range from 500 to 2000 nm. The best fiber coupled devices exhibit detection efficiency of 44.5% at 1310 nm wavelength and 35.5% at 1550 nm ...

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 ...

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 ...

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 ...

Spectral characteristics of WSi and NbN superconducting single-photon detectors with different surface resistance and width of nanowire strips have been investigated in the wavelength range of 1.3-2.5 µm. WSi structures with narrower strips demonstrated better performance for detection of single photons in longer wavelength range. The difference in normalized photon count rate for such structures ...

The developed mathematical model is based on the Galerkin method. Theoretical investigations are proved by Brillouin light scattering spectroscopy.

Spin waves in noncollinear magnets with Cnv symmetry are discussed in the context of inelastic neutron scattering in small-angle scattering geometry. In the framework of aminimal model including exchange coupling, Dzyaloshinskii-Moriya interaction (DMI), and single-ion anisotropy, we consider the system properties at moderate external magnetic fields and in the high-field fully polarized phase. In the latter case, the ...

Using the Kubo formalism we have calculated the local dynamic conductivity of a bulk, i.e., three-dimensional (3D), Dirac semimetal (BDS). 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 ...

High-quality aluminum films on GaAs substrates are studied experimentally. The critical temperature of superconductivity is found to increase markedly with decreasing the film thickness. The observed phenomenon is considered as a manifestation of the quantum confinement effect, which affects both the density of states and the electron–phonon interaction. ...

We demonstrate that two surface waves propagating at a small angle 2θ to each other generate large-scale (compared to the wavelength) vertical vorticity owing to hydrodynamic nonlinearity in a viscous fluid. The horizontal geometric structure of the induced flow coincides with the structure of the Stokes drift in an ideal fluid, but its steady-state amplitude ...
