We investigate the metamaterial with the structure comprising alternating semiconductor layers with intrinsic and metallic conductivity that can be grown epitaxially. The metamaterial is designed to demonstrate artificially low dispersion of the refractive index for the efficient second harmonic generation.
We report on numerical simulations of quantum-dot heterostructures derived from experimental high-resolution transmission electron microscopy results. A real sample containing large InGaN islands with size of ten of nm and non-uniform In content is analyzed. The three-dimensional models for the quantum dots have been directly extrapolated from experimental results by a numerical algorithm. We show...
This paper presents the synthesis technology and electrical properties of porous silicon dioxide films made by magnetron sputtering of the composite target (Si:C) in the oxygen atmosphere. Such method is fully compatible with the existing stages of integrated circuits production implemented in the majority of cases in vacuum conditions.

This article presents research results of optical and electric properties of transparent ITO electroconductive films, their change at the variation of the drawing mode films with the method of magnetron sputtering. The technological mode that helps to receive ITO 100 nanometers thick films with superficial resistance of 10 Ω/□ and transmission coefficient of 87% is described.
Plasma-sustained arcs have been studied that occurred at probes inserted into the tokamaks TM1-MH (Prague) and Tuman 3 (Leningrad). Arc ignition was correlated with spikes of the plasma potential with respect to the wall. From the electrkal characteristks of the arcs it is concluded that the arc channel consists of a thin filament, having rather high inductances, and consisting sometimes of several...
