Investigation of changes in the paramets of thin films structures during ion implantation

Abstract

In this paper were investigated the change of parameters of structures of thin film during ion implantation. Thickness of thin films before and after ion implantation were investigated by X-ray reflectivity. Also, crystal structure, average crystallite size and lattice constant were investigated by X-ray diffraction. The possibility of using ion implantation technique as method of changing grains size in structures was demonstrated.

Bipolar resistive switching in memristive thin films based on Si-Ag

Abstract

In this work were investigated surface and electrophysical properties of multilayer thin film structures based on Si/Ag, grown by Ion-Plasma Deposition method. There were developed and optimized method of structure formation, which consist of silver clusters in silicon medium. Current-voltage curves were observed on prepared structures and demonstrate resistive switching behavior.

Creation of the effective cathode jack for the micro-SPD

Abstract

This paper presents the scope of challenges which are faced in development and manufacturing of the cathode-compensator dedicated for micro-SPTs, and possible ways of how to overcome them. As compared to standard models, such a cathode shall be smaller in dimensions, shall have a lover propellant flow rate, as well as lover heater power and power consumption when self-operated; and it shall be able to operate in the current range of 0.3…1A or lower.

Thermal calculation of the anode of the stationary plasma engine

Abstract

The paper includes the thermal calculation of the anode gas distributor in Stationary Plasma Thruster (SPT) discharge system made with SolidWorks Software, that allows to determine with sufficient accuracy the model’s sensibility vs. variation of the different parameters. The calculation can define the minimum area of fusion penetration between anode’s components during braising in order to obtain the thermal picture of the item design.
