(2019) Kargin, N. I.; Gusev, A. S.; Ryndya, S. M.; Timofeev, A. A.; Grekhov, M. M.; Siglovaya, N. V.; Antonenko, S. V.; Каргин, Николай Иванович; Гусев, Александр Сергеевич; Рындя, Сергей Михайлович; Тимофеев, Алексей Афанасьевич; Сигловая, Наталия Владимировна; Антоненко, Сергей Васильевич
© 2019, Pleiades Publishing, Ltd.Abstract: In this paper, submicron SiC thin films are obtained on α-Al2O3 (0001) substrates from a ceramic target in vacuum by means of pulsed laser deposition. The influence of the substrate temperature on the composition, structure and surface morphology of the experimental samples is studied using scanning and transmission electron microscopy, scanning probe microscopy, X-ray diffractometry, Fourier transform infrared spectroscopy and Raman spectrometry. It is shown that at Tsub = 1000°C the heteroepitaxial growth of 3C-SiC is observed with the following preferential orientation with respect to the substrate: [0001]Al2O3||[111]SiС and [211A]Al2O3||[211]SiС, [100]Al2O3||[(Formula presented.)]SiС. The shape of the reflections from the {011} and {131} 3C–SiC planes on the electron diffraction pattern indicates the presence of local regions in the film that are rotated at angles of up to 7.5° around the growth axis. Thus, it is found that the 3C–SiC film obtained on α‑Al2O3 at a substrate temperature of 1000°C has a mosaic structure partially compensating for the mechanical stresses arising from a mismatch between the lattice parameters and thermal-expansion coefficients along the basal plane.

Measurements of multiplicity fluctuations of identified hadrons in inelastic proton–proton interactions at the CERN Super Proton Synchrotron: NA61/SHINE Collaboration
(2021) Acharya, A.; Adhikary, H.; Aduszkiewicz, A.; Allison, K. K.; Brandin, A.; Golosov, O.; Kargin, N.; Kashirin, E.; Morozov, S.; Selyuzhenkov, I.; Strikhanov, M.; Taranenko, A.; Брандин, Андрей Владимирович; Голосов, Олег Владимирович; Каргин, Николай Иванович; Стриханов, Михаил Николаевич; Тараненко, Аркадий Владимирович
© 2021, The Author(s).Measurements of multiplicity fluctuations of identified hadrons produced in inelastic p+p interactions at 31, 40, 80, and 158 Ge/c beam momentum are presented. Three different measures of multiplicity fluctuations are used: the scaled variance ω and strongly intensive measures Σ and Δ. These fluctuation measures involve second and first moments of joint multiplicity distributions. Data analysis is preformed using the Identity method which corrects for incomplete particle identification. Strongly intensive quantities are calculated in order to allow for a direct comparison to corresponding results on nucleus–nucleus collisions. The results for different hadron types are shown as a function of collision energy. A comparison with predictions of string-resonance Monte-Carlo models: Epos, Smash and Venus, is also presented.

Numerical Optimization of Grating Coupler Parameters for InP-based Photonic Circuits
(2019) Grishakov, K. S.; Kargin, N. I.; Гришаков, Константин Сергеевич; Каргин, Николай Иванович
© 2019 IEEE.We have performed 2D finite-difference time-domain (FDTD) simulations of fiber to chip coupling. The experimental semiconductor structure of the waveguide based on In-GaAsP /InGaAIAs compounds was used in the calculations. This structure is intended for use in electro-optical modulators constructed according to the Mach-Zehnder scheme. Our numerical calculations showed that a simple uniform grating couplers have extremely low coupling efficiency of about 5% for InP-based waveguides. We performed a global optimization of the grating coupler parameters such as etch depth, thickness, period, angle of the grating in relation to the waveguide, etc. We demonstrated a maximal coupling efficiency of about 60% which can be further increased by optimizing a number of other parameters.

Upconversion Luminescence from Sol-Gel-Derived Erbium- and Ytterbium-Doped BaTiO3 Film Structures and the Target Form
(2023) Gaponenko, N. V.; Staskov, N. I.; Sudnik, L. V.; Martynov, I. L.; Chistyakov, A. A.; Kargin, N. I.; Labunov, V. A.; Мартынов, Игорь Леонидович; Чистяков, Александр Александрович; Каргин, Николай Иванович; Лабунов, Владимир
Sol-gel technology has attracted attention in the fabrication of diverse luminescent materials and thin film structures, with forms that range from powders to microcavities. The optical properties of sol-gel-derived structures depend on the sol composition, deposition, and heat treatment conditions, as well as on the film thicknesses and other factors. Investigations on the upconversion luminescence of lanthanides in film structures and materials are also ongoing. In this study, we synthesized three different types of materials and film structures using the same sol, which corresponded to a Ba0.76Er0.04Yb0.20TiO3 xerogel, as follows: (a) the target form, which used the explosive compaction method for sol-gel-derived powder; (b) single-layer spin-on xerogel films annealed at 450 and 800 В°C; and (c) microcavities with an undoped SiO2/BaTiO3 Bragg reflector surrounding a Ba0.76Er0.04Yb0.20TiO3 active layer. The BaTiO3:(Er,Yb)/SiO2 microcavity exhibited an enhancement of the upconversion luminescence when compared to the BaTiO3:(Er,Yb) double-layer film fabricated directly on a crystalline silicon substrate. The reflection spectra of the BaTiO3:(Er, Yb)/SiO2 microcavity annealed at 800 В°C demonstrated a deviation of the maxima of the reflection within 15% for temperature measurements ranging from 26 to 120 В°C. From the analyses of the transmission and reflection spectra, the optical band gap for the indirect optical transition in the single layer of the BaTiO3:(Er,Yb) spin-on film annealed at 450 В°C was estimated to be 3.82 eV, while that for the film annealed at 800 В°C was approximately 3.87 eV. The optical properties, upconversion luminescence, and potential applications of the BaTiO3:(Er,Yb) sol-gel-derived materials and structures are discussed in this paper.

A method of parameterization of supersmooth surfaces used in micro- and nanoelectronics as substrates and light-reflecting elements is proposed. The method is based on the flicker-noise spectroscopy (FNS) as the general phenomenological approach to extracting information from the chaotic temporal or spatial signals. The glass-ceramic samples were processed by cluster-ion beams and their topology was investigated by atomic force microscopy before and after treatment. It is established that gas cluster ion beams processing of glass ceramics leads to angstrom-level surface roughness.

(2022) Acharya, A.; Adhikary, H.; Allison, K. K.; Amin, N.; Brandin, A.; Golosov, O.; Kargin, N.; Kashirin, E.; Morozov, S.; Selyuzhenkov, I.; Strikhanov, M.; Taranenko, A.; Брандин, Андрей Владимирович; Голосов, Олег Владимирович; Каргин, Николай Иванович; Стриханов, Михаил Николаевич; Тараненко, Аркадий Владимирович
© 2022, The Author(s).The production of KS0 mesons in inelastic p+p collisions at beam momentum 158 GeV/c (sNN=17.3 GeV) was measured with the NA61/SHINE spectrometer at the CERN Super Proton Synchrotron. Double-differential distributions were obtained in transverse momentum and rapidity. The mean multiplicity of KS0 was determined to be 0.162 ± 0.001 (stat.) ± 0.011 (sys.). The results on KS0 production are compared with model predictions (EPOS 1.99, SMASH 2.0, PHSD and UrQMD 3.4 models) as well as with published world data.

© 2021, The Author(s).The physics goal of the strong interaction program of the NA61/SHINE experiment at the CERN Super Proton Synchrotron (SPS) is to study the phase diagram of hadronic matter by a scan of particle production in collisions of nuclei with various sizes at a set of energies covering the SPS energy range. This paper presents differential inclusive spectra of transverse momentum, transverse mass and rapidity of π- mesons produced in central40Ar+45Sc collisions at beam momenta of 13A, 19A, 30A, 40A, 75A and 150AGeV/c. Energy and system size dependence of parameters of these distributions – mean transverse mass, the inverse slope parameter of transverse mass spectra, width of the rapidity distribution and mean multiplicity – are presented and discussed. Furthermore, the dependence of the ratio of the mean number of produced pions to the mean number of wounded nucleons on the collision energy was derived. The results are compared to predictions of several models.

© 2021, Pleiades Publishing, Ltd.Abstract: The results of this study quantitatively and qualitatively illustrate the processes of mismatch stress relaxation upon epitaxy of cubic silicon carbide on silicon. The mechanical stress distribution in 3C–SiC/Si and 3C–SiC/por-Si heterostructures is analyzed. It is shown that a porous buffer layer plays a role in the reduction of mismatch stress. The data of the theoretical study are verified by experimental residual stress in 3C–SiC/Si and 3C–SiC/por-Si samples.
