Technological features of DC and RF magnetron spatering

2019-09-26T17:56:14+00:00

The analysis of technological features of DC- and RF-magnetron discharges processes was carried out. It is shown that distinctions in the formation and maintenance of the plasma sheath have different effects on the sputtered and deposited material. Plasma potentials and particle fluxes onto the substrate are the main factors of the energy bombardment of the substrate, and are highly dependent on the technological features of the sputtering system.

The paper proposes a method of nondestructive testing and reliability of housings facilities for disinfecting water by ultraviolet radiation. The design concept of the radiation chamber of installations is described. The method of theormographic control of the integrity of the radiation chamber was tested. The prospects of a wider introduction of installations for industrial and energy enterprises are analyzed.

Transition photoelectric processes in a superfluid gas-discharge cell with semiconductor electrodes

2019-09-26T18:00:27+00:00

In this paper, transient photoelectric processes in a hyperfine gas-discharge cell were investigated. The issues of delay of the gas discharge breakdown in the pulsed mode of the cell operation and the electrostatic phenomena of the transient processes are considered. It is established that the breakdown delay time depends on the semiconductor illumination intensity, the duration and magnitude of the voltage pulse, and also the state of the surface charge, that is, the field strength of the surface charges.

Synthesis of ordered nanostructures based on carbon nanotubes

2019-09-26T18:25:56+00:00

Aligned carbon nanotubes (CNTs) on a metal plate with parallel or perpendicular directivity was synthesized by vacuum-arc method.. Some advantages growing of CNTs directly on the surface of bulk metals are defined. The presence of good electrical contacts of nanostructures with the substrate is established. The main physical and technological characteristics of the obtained ordered nanostructures are determined. Technological conditions and parameters under which it is possible to obtain a forest of nanotubes are reported. The obtained ordered nano-sized structures from CNTs can be used for the manufacture of electronic devices and the development of new composite materials with unique properties.
