Adaptive interferometry with photorefractive (PR) crystals [1] is well known as robust and effective measuring technique for detection of quite small physical quantities (e.g. ultra-weak vibrations with amplitude of 1 nm and below) in unstable (e.g. industrial) environment. There are a number of practical tasks where not one but several quantities are to be simultaneously measured. If so, a multichannel measurement system is required.

A set of silicon substrates processed by compression plasma was studied by means of atomic force microscopy (AFM). AFM data revealed a threshold nature (in terms of plasma flow energy) of the formation of tube-like surface structures (SS) observed as “waves” regardless of the conductivity type, resistivity, and the substrate orientation ((111) or (100)). For the first time nanoheterostructures Si(111)/NC CrSi 2 /Si and Si(100)/NC β - FeSi 2 / Si have been formed on silicon substrates processed by compression plasma flow. Avery high density of CrSi 2 nanoislands — (2–3)×10 11 cm −2 was obtained for Cr–Si system but in the case of Fe–Si system the β - FeSi 2 nanoislands density was only about 2×10 9 cm −2 . According to the optical spectroscopy data during the process of silicon capping layer formation the CrSi 2 and β - FeSi 2 nanocrystals move up to the surface.

Semiconducting CrSi 2 nanocrystals (NCs) with high density (4×1010 cm −2 ) and narrow size distribution were grown by reactive deposition epitaxy (RDE) of 0.6 nm Cr at 550 °C on Si(111)7 × 7 substrate. Based on DRS, AFM and TEM results silicon cap epitaxy growth procedure on silicon with high density of CrSi 2 NCs has been proposed. Monolithic Si(111)/ CrSi 2 NCs/Si(111) structures with three layers of buried CrSi 2 NCs have been successfully grown by repeating of CrSi 2 NCs formation and silicon epitaxial growth. Electrical characterization of Schottky junctions formed on the grown structures has shown that the formation of point defects generated during the growth of the Si cap layer strongly depends on the cap growth conditions and on the Cr deposition rate.

To study structural and transport properties of the surface phases on silicon, a number of adsorbate/silicon systems on Si(100) and Si(111) surfaces has been investigated using scanning tunneling microscopy (STM), reflection-high-energy-electron diffraction (RHEED) and in-situ electrical resistance measurements. Results of investigations of formation and electrical properties of Si-Al, Si-Na, Si-Ag and Si-In surface structure are presented.

During AES and EELS investigations of thermal stability of Mg and Mg 2 Si films it was found that metallic Mg desorbs from the surface at temperatures higher than 80 °C, but the bulk-like Mg 2 Si film shows a thermal stability up to 180 °C. The maximal thermal stability up to 230 °C was observed for a two-dimensional magnesium silicide with structure (2/3√3×2/3√3)- R 30°. A model of its thermal stability based on the peculiarities of the electronic structure of a two-dimensional magnesium silicide with structure (2/3√3×2/3√3)- R 30° and on the continuity of 2D film was proposed.

The mechanical fragmentation of the droplet as a result of the evaporation and explosion of superheated areas is also discussed. The spectral characteristics of water particle emission during its explosive boiling are investigated.
