In this work the combination method of three-dimensional models of processed details with their reference CAD-models when these details have unknown in advance deformation is proposed. This method assumes preliminary transformation of models to clouds of points, special density increasing of these clouds and their iterative combination by means of ICP (Iterative Closest Points) algorithm. Model example demonstrates the efficiency and effectiveness of proposed approach. © 2016 IEEE.

(Tl, Au)/Si(1 1 1)[Formula: see text] 2D compound: an ordered array of identical Au clusters embedded in Tl matrix

Journal of physics. Condensed matter : an institute of Physics journal 2018年第2期30卷 025002页

Formation of the highly-ordered [Formula: see text]-periodicity 2D compound has been detected in the (Tl, Au)/Si(1 1 1) system as a result of Au deposition onto the Tl/Si(1 1 1) surface, its composition, structure and electronic properties have been characterized using scanning tunneling microscopy, angle-resolved photoelectron spectroscopy and density-functional-theory calculations. On the basis of these data, the structural model of the Tl-Au compound has been proposed, which adopts 12 Tl atoms and 10 Au atoms (in total, 22 atoms) per [Formula: see text] unit cell, i.e. ∼1.71 ML of Tl and ∼1.43 ML of Au (in total, ∼3.14 ML). Qualitatively, the model can be visualized as consisting of truncated-pyramid-like Au clusters with a Tl atom on top, while the other Tl atoms form a double layer around the Au clusters. The (Tl, Au)/Si(1 1 1)[Formula: see text] compound has been found to exhibit pronounced metallic properties at least down to temperatures as low as ∼25 K, which makes it a promising object for studying electrical transport phenomena in the 2D metallic systems.

Fabrication of porous nanostructures for Raman signal amplification

Journal of Physics: Conference Series 2018年第1期951卷

作者： E V Mitsai S A Syubaev A A Kuchmizhak Institute of Automation and Control Processes FEB RAS 5 Radio Str. 690041 Vladivostok Russia Far Eastern Federal University 8 Sukhanova Str. 690090 Vladivostok Russia

Pulsed-laser dry printing of noble-metal microrings with a tunable internal porous structure, which can be revealed via an ion-beam etching post-procedure, was demonstrated. Average size of the pores inside the microrings were shown to be tuned in a wide range by varying the incident pulse energy and a nitrogen doping level controlled in the process of magnetron deposition of the gold film in the appropriate gaseous environment. The fabricated porous microrings were shown to provide many-fold near-field enhancement of incident electromagnetic fields, which was confirmed by mapping of the characteristic Raman band of a nanometer-thick covering layer of Rhodamine 6G molecules and supporting calculations. The proposed laser-printing/ion-beam etching approach is demonstrated to be a unique tool aimed at designing and fabricating multifunctional plasmonic structures and metasurfaces for spectroscopic bioidentification based on surface-enhanced Raman scattering and photoluminescence detection schemes.

The paper presents the method for processing of excitation-emission matrix of sea water and the allocation of the spectral characteristics of different types of colored dissolved organic matter (CDOM) and phytoplankton cells in seawater. The method consists of identification of regularly observed fluorescence peaks of CDOM in marine waters of different type and definition of the spectral ranges, where the predominant influence of these peaks are observed.

Theory versus experiment for a family of single-layer compounds with a similar atomic arrangement: (Tl,X)/Si(111)3×3(X=Pb,Sn,Bi,Sb,Te,Se)

Physical Review B 2017年第8期96卷 085409-085409页

作者： A. V. Matetskiy I. A. Kibirev A. N. Mihalyuk S. V. Eremeev D. V. Gruznev L. V. Bondarenko A. Y. Tupchaya A. V. Zotov A. A. Saranin Institute of Automation and Control Processes FEB RAS 690041 Vladivostok Russia School of Natural Sciences Far Eastern Federal University 690091 Vladivostok Russia Institute of Strength Physics and Materials Science 634021 Tomsk Russia Department of Physics Tomsk State University 634050 Tomsk Russia

Two-dimensional compounds made of one monolayer of Tl and one-third monolayer of Pb, Bi, Te, or Se (but not of Sn or Sb) on Si(111) have been found to have a similar atomic arrangement which can be visualized as a 3×3-periodic honeycomb network of chained Tl trimers with atoms of the second adsorbate occupying the centers of the honeycomb units. Structural and electronic properties of the compounds have been examined in detail theoretically using density functional theory (DFT) calculations and experimentally using low-energy electron diffraction (LEED), scanning tunneling microscopy (STM), and angle-resolved photoelectron spectroscopy (ARPES) observations. It has been found that though structural parameters of the compounds are very similar for all species, the only common feature of their band structure is a considerable spin-splitting of the surface-state bands, while other basic electronic properties vary greatly with a change of species. The Tl-Pb compound is strongly metallic with two metallic surface-state bands; the Tl-Bi compound is also metallic but with a single metallic band; the Tl-Te and Tl-Se compounds appear to be insulators.

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.

Here we present a simple technique for copper (II) detection in aqueous solutions by luminescent dye doped polymer film. In this study the photoluminescent dye (2-(benzoylamino)-3-[4-(dimethylamino)phenyl]-2-propenoic acid) was embedded in thin chitosan films. The sensor response was formed by quenching the dye luminescence. This technique can offer a rapid detection of Cu2+ with a dynamic range up to 350 µM. © (2016) Trans Tech Publications, Switzerland.

The results of mathematical modeling of the dynamic interaction of a plane longitudinal shock wave with a plane interface between two isotropic nonlinear elastic materials are presented. The mechanical properties of deformable solid are given by the elastic Murnaghan model. The dynamic processes of deformations distribution are studied in the framework of the theory of singular surfaces. The numerical solutions of the corresponding self-similar problem with strong and weak deformations discontinuities in the reflected and refracted wave packages have been obtained on the basis of the developed scheme of computational experiment. © 2016 Trans Tech Publications, Switzerland.

Formation of GaSb by means of solid phase epitaxy of amorphous Ga:Sb (1:1) layer on Si(001) substrate at 500°C has been studied. At amorphous layer thickness of 16 nm, a continuous nanocrystalline layer of GaSb was formed. Decreasing of amorphous layer thickness up to 0.8 nm resulted in formation of separated GaSb nanocrystallites (NCs), which had a mean lateral size of 30–80 nm and mean height of 2–3 nm, while their concentration reached 3×109 cm-2. Atomic force microscopy and low energy electron diffraction data showed that GaSb NCs could be fully embedded into silicon lattice by deposition of 25-nm-thick silicon layer at 650°C. Nevertheless, on a surface of the silicon layer, some holes have been formed because of NCs moving toward to the surface. The holes formation can be almost completely suppressed by deposition of additional 25-nm-thick silicon layer at 500°C – so-called "stop-layer". © (2016) Trans Tech Publications, Switzerland.
