Modeling of the effect of field electron emission from the cathode with a thin dielectric film on its effective secondary electron emission yield in gas discharge plasma
Ch. 3. P. 178–181.
In this work, a model describing the field emission of electrons from the electrode metal substrate into the insulating film, their motion in the film and going out of it into the dischargevolume is formulated. An analytical expression for the film emission efficiency is obtained and its dependence on the film parameters is studied.

For the first time we study kink oscillations of braided coronal magnetic loops. We use the simplest model of a braided loop that consists just of two identical curved magnetic tubes. It is assumed that the plasma density is constant inside the tubes, and also in the surrounding plasma. To describe the kink oscillations we ...

Сформулирована модель тлеющего газового разряда в смеси аргона и паров ртути при наличии
на поверхности катода тонкой диэлектрической пленки. Рассчитаны зависимости характеристик
разряда от температуры в интервале ее изменения, в котором заметный вклад в ионизацию
рабочей газовой смеси дает ионизация атомов ртути метастабильными возбужденными атомами
аргона (реакция Пеннинга). Показано, что в случае катода без диэлектрической пленки при
повышении температуры до ...

This work presents a comprehensive investigation into the temperature-dependent thermally stimulated conductivity and photoconductivity of vacuum-annealed thin films based on core–shell CdSe/CdS nanoplatelets passivated with oleic acid ligands. Controlled thermal annealing under vacuum conditions leads to a substantial increase in both dark and photoinduced conductivity, which is primarily attributed to partial desorption of the ligands. ...

This work is devoted to an experimental study of the influence of the nonuniformity distribution of a thin (5–10 nm)
superconducting NbN film on the properties of individual pixels in an HEB mixer array fabricated from it. The studies were conducted at different Si substrate temperatures, with Tc near Tc and Tc well below Tc. This ...

We study standing non-linear sausage waves in coronal loops with the plasma temperature varying with time. In our analysis we use the simplest model of a coronal loop in the form of a straight magnetic tube with a circular cross-section. We also assume that the plasma-beta is low. This enables us to neglect the magnetic ...

We review studies of physical processes associated with the impact of external factors in outer space — flows of micrometeoroids and solar radiation — on the lunar regolith. Under the influence of these factors, regolith microparticles can detach from the surface and levitate. Near-surface plasma and levitating dust particles form a plasma-dust exosphere of the ...

The separation of Pb nanoislands on the vicinal surface of Si(7 7 10) into layers 2 nm thick, caused by quantization of the electronic spectrum, implies the formation of two-dimensional defects separating the Pb layers. Using model calculations in the density functional theory approximation, it was shown that the twin boundary has the minimum energy ...

We study oscillations of two parallel interacting magnetic tubes in the presence of plasma flow along the tubes. Using the cold plasma and thin tube approximations we derive the system of two equations describing these oscillations. This system of equations is valid for equilibria where the plasma density and flow velocity can vary along the ...

In this article we study the effect of a transitional layer in a magnetic tube on the real part
of the frequencies of kink oscillations. In our analysis, we use the model of a straight magnetic tube with the density and cross-section radius varying along the loop, and the thin-tube
thin-boundary (TTTB) approximation. First, we calculate the ...
