Resistivity, ρ (T), and Hall coefficient in weak (B −1 plots at lower and higher T, and a weak increase between T ~ 200 − 300 K. Both materials demonstrate a complex dependence of R (T), including a change of the sign. Transport properties above have been analyzed assuming two groups of charge carriers, electrons and holes, contributing them. © 2020 Trans Tech Publications Ltd, Switzerland.

Highly regular thermochemical laser-induced periodic surface structures (TLIPSS) were produced on the surface of TiN, CrN and Ge3N4 glass-supported thin films using femtosecond IR-and visible-range laser pulses. Systematic studies of the TLIPSS morphology variation as a function of key laser processing parameters and ambient atmosphere revealed the processing regimes providing high-regular 2D and 3D morphologies promising for optical and optoelectronic applications. © 2022 IEEE.

The growth, structure, optical, electrical and thermoelectric properties of calcium silicides of various compositions on silicon substrates with (100) and (111) orientations were experimentally studied. It was found that when the atoms of Ca and Si are co-deposited on atomically clean silicon, the basis phases in the composition of the formed films depends on the substrate temperature and the annealing temperature: Ca2Si (TSi = 20oC, Tann = 330oC), CaSi (TSi = 190-320oC, Tann = 330°C) and CaSi2 (TSi = 500°C). It was established that the Ca2Si phase is a direct-gap semiconductor with a band gap of 0.82±0.02 eV, large contribution of defect levels to the absorption coefficient at energies 0.25 - 0.50 eV and huge transmission up 90% in the far IR region. In CaSi-based films the high transmission (30-40%) up to 25 μm was observed, which corresponds to a semimetal with a constant density of states near the Fermi level. It was found that CaSi-based films have the maximum Seebeck coefficient and the power factor (up to 430 μV/K and up to 1.14×10-6 W/(K2×m), respectively) at 330K. CaSi2 films with CaSi2 lattice stretching and epitaxial ordering relative to the Si(100) substrate exhibit semimetal properties, with very high conductivity and light transparency (up 12%) in the photon energy range 0.06 - 0.65 eV. © 2018 Trans Tech Publications, Switzerland

The paper discusses tomography reconstruction of distributed physical fields by means of distributed fiber optical measuring systems (FOMN) for incomplete parallel schemes of measuring lines (ML) stacking. The approach is presented, consists in optimization of geometry of a measuring network for the purpose of the further application neural network methods of restoration of a full-image of investigated functions. Possibility of a choice and use of a suitable neural network from set of the several, in advance trained, neural networks of RBF-type is investigated. © 2010, Institution of Russian Academy of Sciences.

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. © 2011 IEEE.

Here we report on the study of a novel class of nanocomposites for optical control devices. It was observed that the nanocomposites based on cadmium sulfide quantum dots in silica matrix change their optical properties under UV-light irradiation. The changes are expressed in optical absorbance coefficient increasing and luminescence intensity decreasing, which are accompanied by red-shifting of the luminescence maximum in some cases. Dependences of quantum dot optical properties upon the matrix kind and polarization degree of modifying radiation were obtained. © (2016) Trans Tech Publications, Switzerland.

The paper presents a fault accommodation system for electric servo actuators of underwater manipulators. These actuators are described by nonlinear equations with variable parameters. It is assumed, that the following typical faults are possible in electric servo actuators: fault caused by changing of viscous friction moment and error in the sensor, which measures the position of output shaft of gear. The proposed system is based on using of diagnostic observers with residual signal feedback. It is proposed the methodology of synthesis of such observers for detection and identification of occurred faults. The accommodation to faults is ensured due to the generation of additional control signals based on identified value of faults. This provides the reliability of underwater working of manipulators at faults. The efficiency of the proposed system is confirmed by mathematical modelling.

Optimization of growth parameters has permitted to create monolithic nanocomposites with buried nanocrystallites (NCs) of iron and chromium disilicides, polycrystalline nanocomposites with buried Mg2Si NCs and epitaxial MnSi1.74 nanoislands on Si(111) substrate. Grown quasi-zero dimensional heterostructures with multilayers of β-FeSi2 NCs atop silicon p-n junction have demonstrated the range expansion of photoelectrical sensitivity up to 1.8 μm and strong room temperature electroluminescence at 1.2 - 1.6 μm. A new approach to the selective doping of embeddded nanocrystallites inside silicon matrix has been developed on the base of the successive formation of ordered superstructures of metals (Ag, Sb) together with silicide island formation. Nanocomposite layers with n- and p-type conductivity and huge Seebeck coefficient (550-750 μV/K) in the Si-p/β-FeSi2 NCs/Si-p and Si/Mg2Si NCs/Si-p and Si/Mg2Si NCs/Si-n nanocomposites have been created and tested. © 2013 WILEY-VCH Verlag GmbH & Co.

Highly regular thermochemical laser-induced periodic surface structures (TLIPSS) were produced on the thin Ti metal film deposited on a curved side surface of optical fiber using femtosecond IR laser pulses. The significant dependence of structures regularity on the laser polarization direction relative to the fiber axis was revealed. Results of TLIPSS formation on fiber tip and their practical applications are presented. © 2024 IEEE.
