WSi thin films have the advantages for creating SNSPDs with a large active area or array of detectors on a single substrate due to the amorphous structure. The superconducting properties of ultrathin WSi films substantially depends on their structure and thickness as the NbN films. Scientific groups investigating WSi films mainly focused only on changes of their thickness and the ratio of the components on the substrate at room temperature. This paper presents experiments to determine the effect of the bias potential on the substrate, the temperature of the substrate, and the peak power of pulsed magnetron sputtering, which is the equivalent of ionization, a tungsten target, on the surface resistance and superconducting properties of the WSi ultrathin films. The negative effect of the substrate temperature and the positive effect of the bias potential and the ionization coefficient (peak current) allow one to choose the best WSi films formation mode for SNSPD: substrate temperature 297 K, bias potential −60 V, and peak current 3.5 A.

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 reaches one order of magnitude higher in comparison with structures based on NbN thin films at 2.5 µm.

We have investigated processes of modification and changing of the charge state of MOS structures having a multilayer gate dielectric based on a thermal SiO2 film doped with phosphorus under conditions of different modes of high-field electron injection and an electron irradiation. We have determined that negative charge, accumulating in the phosphosilicate glass (PSG) ultra thin film of the MOS structures having the two-layer gate dielectric SiO2-PSG under conditions of both high-field tunneling injection of electrons and electron beam, could be used for a modification of devices having the same structure (e.g. correction of threshold voltage, increase of charge stability and breakdown voltage of MOS structure). We have shown that when thickness of PSG film increased, a raising of the electron traps density occurred, but the value of the cross-section of electron traps was the same. It was established that in order to obtain MOS structures with high thermal stability, one has to anneal them at 200° C after performing irradiation treatment.

В работе предложен новый метод многоуровневой токовой нагрузки для исследования тонких оксидных слоев МОП (металл-окисел-полупроводник) структур. Метод позволяет изучать генерацию и релаксацию положительных и отрицательных зарядов в нанотолщинном подзатворном диэлектрике МОП-структуры в различных стрессовых ситуациях. Параметры, характеризующие изменение зарядового состояния  тонких оксидных слоев МОП - структур в процессе инжекции  контролировались с помощью измерения временной зависимости падения напряжения, приложенного к образцу. В сравнении с известными методами, предложенный в данной работе метод является неразрушающим, обеспечивает более высокую точность и уменьшает возможность  электрического пробоя диэлектрика. С использованием данного метода в работе выполнено исследование зарядовой генерации и релаксации во время и после сильнополевой туннельной инжекции электронов в тонкой пленке двуокиси кремния. Исследовано также влияние плазменного и радиационного воздействий на тонкие оксидные слои МОП-структур.

The work has to do with optimization of vacuum-free material working processes with using the concentrated electron beam. A method for direct experimental determination of primary electrons local characteristics in the dense gaseous medium was proposed. The meter design and the measurement procedure were described. The analytical method for evaluation of the electron beam local parameters in the dense gaseous medium was developed. The method was used for evaluation of kinematic characteristics of detector displacement device. © Published under licence by IOP Publishing Ltd.

The article describes the advantages of the new technology of mineral coating of metal products for the friction pair of mechanical systems. It presents the research results of the wear rate of the samples made of 12X13 steel (X12Cr13) with mineral layers, in the experiments with a piston ring sliding inside a cylinder liner with grease. The wear rate of the samples with mineral layers is lower almost by two factors than that of the samples made of grey foundry iron and untreated samples. As the result of slip/rolling abrasion tests of parts with mineral layers under conditions of high contact pressure, a suggestion was made concerning probable mechanics of surface wear.
