“…This connection was more pronounced in photocells having a low dopant concentration with the formation of low energy levels. For example, on heat-treated photocells, impurities in the original silicon (boron or phosphorus), which form small energy levels, go into the compensation position [28][29][30][31]. As a result of interaction with impurities that form deep energy levels, the values of U o.c.v.…”

Currently, there is a growing need for high-performance photocells with increased stability of parameters to external influences, such as thermal and radiation resistance. This work is devoted to the study of photocells available in the volume of an ordered micro-and nanostructure based on silicon doped with impurity nickel atoms. The study of the formation of micro-and nanoclusters of impurity atoms in silicon photocells that were subjected to additional high-temperature processing makes it possible to determine the degradation of nickel clusters, which strongly affect the electrical parameters of photocells. It is shown that impurity nickel atoms will increase the stability of the electrophysical parameters of photocells under the influence of both high temperature and radiation. The results obtained in the study showed that the introduction of nickel impurity atoms into the volume of silicon-based photocells leads to temperature and radiation resistance, and also increases efficiency.

“…For large factories of hoisting and transport equipment, such metal savings could be 2000 tons per year, which is equivalent to an additional production of 100 cranes [43][44][45][46][47][48][49][50][51][52][53][54][55][56][57].…”

This work is devoted to the study of multi-machine systems of coordinated rotation of the engines of handling equipment. The purpose of the work is to identify, by theoretical calculation, the reduction in the metal consumption of cranes equipped with multi-motor electric drives and operating on the principle of an electromagnetic working shaft, in comparison with the current ones. The analysis of the shifting moments of these systems in dynamics was made and conclusions were drawn about the reduction in the weight of the metal structures of cranes and the saving of metal in their production.

“…In recent years, we have used implantation of Ba + ions into CdTe and CdS [11,12] to obtain doped single crystalline layers and Cd 1 -x Ba x Te and Cd 1 -x Ba x S surface and subsurface layers. Earlier, analogous two-and three-component nanostructures were obtained by ion implantation on the surfaces of Si, GaAs, and SiO 2 [13][14][15]. Results of these investigations showed that the electron-band parameters, electron emission, and optical properties of these structures depend on their composition (x) and nanostructure dimensions.…”

“…Single crystals and films of A 2 B 6 semiconductor compounds, in particular CdS, and related multilayer heterostructures are widely used for the creation of various micro-, nano-, and optoelectronic devices, including those for solar power engineering [1][2][3][4]. At present, the influence of heat treatments, laser annealing, microwave processing, and the ion and electron bombardment on the structure, composition, and optical properties of A 2 B 6 compounds and the process of atomic interdiffusion at the interfaces of multilayer systems based on these semiconductors have been thoroughly studied [5][6][7][8][9][10][11][12][13]. In recent years, we have used implantation of Ba + ions into CdTe and CdS [11,12] to obtain doped single crystalline layers and Cd 1 -x Ba x Te and Cd 1 -x Ba x S surface and subsurface layers.…”

We have studied the composition, electron emission, and optical properties of CdS single crystals covered by a surface film of adsorbed Ba atoms with thickness Θ from 0.5 to 5 monolayers (ML). It is established that, as Θ increases up to 1 ML, yield depth λ of true secondary electrons (and photoelectrons) in the emission zone exhibits significant growth, which is explained by decreasing work function of the material surface. The further increase in Θ is accompanied by a decrease in both λ and photocurrent intensity values. It is found that no significant mutual diffusion of atoms at the Ba-CdS interface takes place at room temperature. Upon heating to T = 700 K, sulfur atoms exhibit intense diffusion into the Ba film and form a surface compound of the Ba 2 S type.
