O.; Timofeev, A. A.; Гусев, Александр Сергеевич; Каргин, Николай Иванович; Рындя, Сергей Михайлович; Сафаралиев, Гаджимет Керимович; Сигловая, Наталия Владимировна; Султанов, Азрет Оюсович; Тимофеев, Алексей Афанасьевич© 2019, Pleiades Publishing, Ltd.Abstract: Experimental and theoretical studies of the processes of mesoporous-silicon carbonization during the formation of buffer layers for the subsequent epitaxy of 3C-SiC films and related wide-gap semiconductors are performed. Analytical expressions for the effective diffusion factor and diffusion length of carbon atoms in a porous system are obtained. The proposed model takes into account the processes of Knudsen diffusion, coagulation and the overgrowth of pores during the formation of a silicon-carbide layer.

- ПубликацияТолько метаданныеProton-proton interactions and onset of deconfinement(2020) Aduszkiewicz, A.; Andronov, E. V.; Anticic, T.; Babkin, V.; 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 ВладимировичThe experiment of the NA61/SHINE Collaboration at the CERN SPS is performing a unique study of the phase diagram of strongly interacting matter by varying collision energy and nuclear mass number of colliding nuclei. In central Pb + Pb collisions, the experiment of the NA49 Collaboration found structures in the energy dependence of several observables in the energy range of the CERN SPS that had been predicted for the transition to a deconfined phase. New measurements of the NA61/SHINE Collaboration find intriguing similarities in p + p interactions for which no deconfinement transition is expected at the energies of the SPS. Possible implications will be discussed.

NA61/SHINE, a large-acceptance hadron spectrometer, has recorded hadron+nucleus interactions relevant to ongoing and future long-baseline neutrino experiments at Fermi National Accelerator Laboratory. This paper presents three analyses of interactions of 60 GeV/c π+ with thin, fixed carbon and beryllium targets. Integrated production and inelastic cross sections were measured for both of these reactions. In an analysis of strange, neutral hadron production, differential production multiplicities of KS0, Λ and Λ were measured. Lastly, in an analysis of charged hadron production, differential production multiplicities of π+, π-, K+, K- A nd protons were measured. These measurements will enable long-baseline neutrino experiments to better constrain predictions of their neutrino flux in order to achieve better precision on their neutrino cross section and oscillation measurements.
- ПубликацияТолько метаданныеHidden strangeness shines in NA61/SHINE(2019) Klochkov, V.; Selyuzhenkov, I.; Aduszkiewicz, A.; Andronov, E. V.; Brandin, A.; Golosov, O.; Kargin, N.; Kashirin, E.; Morozov, S.; Strikhanov, M.; Taranenko, A.; Брандин, Андрей Владимирович; Голосов, Олег Владимирович; Каргин, Николай Иванович; Стриханов, Михаил Николаевич; Тараненко, Аркадий ВладимировичPreliminary results on the phi (1020) meson production in inelastic proton-proton collisions measured by the NA61/SHINE experiment at the CERN SPS are presented in these proceedings. The results include the first ever differential P-T and y measurements at beam momenta of 40 and 80 GeV and the most ever detailed experimental data at 158 GeV. The comparison of p + p to Pb + Pb results shows a non-trivial system size dependence of the widths of the rapidity distributions for phi mesons, contrasting with that of other hadrons. The results are furthermore compared to the world data on phi meson production, demonstrating the better accuracy achieved by the NA61/SHINE experiment, and to several models. None of the models is found to be able to describe simultaneously the shape of transverse momentum spectra, the shape of rapidity distribution and the total yield.
- ПубликацияТолько метаданныеEuropium luminescence from amorphous yttrium alumina films on fused silica substrates(2019) Villegas, Brito, J. C.; Sukalin, K. S.; Raichenok, T. F.; Tikhomorov, S. A.; Gaponenko, N. V.; Kargin, N. I.; Гапоненко, Николай Васильевич; Каргин, Николай Иванович© Published under licence by IOP Publishing Ltd. In this work, we investigate photoluminescence of sol-gel derived films corresponding to yttrium alumina garnet Y 3 Al 5 O 12 doped with trivalent europium. The films with three concentrations of europium 0,02; 0,025; 0,03 M with the thickness 210-220 nm were deposited on fused silica substrates by the corresponding sols' spinning followed by drying and high temperature annealing at 1000 °C for 30 min. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) analysis as well as ellipsometry, photoluminescence (PL) and photoluminescence excitation spectroscopy (PLE). All of the fabricated samples were amorphous and revealed roomerature luminescence bands within the range of 550 - 750 nm corresponding to 5 D 0 → 7 F j (j = 0,..,4) transitions of trivalent europium ions with the most intensive bands at 610 - 630 nm and 680 - 710 nm. The intensity of europium luminescence increases with europium concentration. The photoluminescence excitation spectra measured at the emission wavelength 710 nm exhibit strong bands at 220 nm, which could be associated with absorption of exciting light within Eu 3 + - O 2 - bands. Practical application of the obtained films transforming ultraviolet irradiation into visible is discussed.

- ПубликацияТолько метаданныеOptical Properties and Upconversion Luminescence of BaTiO3 Xerogel Structures Doped with Erbium and Ytterbium(2022) Lashkovskaya, E. I.; Martynov, I. L.; Chistyakov, A. A.; Kargin, N. I.; Labunov, V. A.; Raichenok, T. F.; Tikhomirov, S. A.; Timoshenko, V. Yu.; Мартынов, Игорь Леонидович; Чистяков, Александр Александрович; Каргин, Николай Иванович; Лабунов, ВладимирErbium upconversion (UC) photoluminescence (PL) from sol-gel derived barium titanate (BaTiO3:Er) xerogel structures fabricated on silicon, glass or fused silica substrates has been studied. Under continuous-wave excitation at 980 nm and nanosecond pulsed excitation at 980 and 1540 nm, the fabricated structures demonstrate room temperature PL with several bands at 410, 523, 546, 658, 800 and 830 nm, corresponding to the 2H9/2 → 4I15/2, 2H11/2 → 4I15/2, 4S3/2 → 4I15/2, 4F9/2 → 4I15/2 and 4I9/2 → 4I15/2 transitions of Er3+ ions. The intensity of erbium UC PL increases when an additional macroporous layer of strontium titanate is used beneath the BaTiO3 xerogel layer. It is also enhanced in BaTiO3 xerogel films codoped with erbium and ytterbium (BaTiO3:(Er,Yb)). For the latter, a redistribution of the intensity of the PL bands is observed depending on the excitation conditions. A multilayer BaTiO3:(Er,Yb)/SiO2 microcavity structure was formed on a fused silica substrate with a cavity mode in the range of 650–680 nm corresponding to one of the UC PL bands of Er3+ ions. The obtained cavity structure annealed at 450 °C provides tuning of the cavity mode by 10 nm in the temperature range from 20 °C to 130 °C. Photonic application of BaTiO3 xerogel structures doped with lanthanides is discussed. © 2022 by the authors. Licensee MDPI, Basel, Switzerland.

- ПубликацияТолько метаданныеAnisotropy of Assemblies of Densely Packed Co-Alloy Nanoparticles Embedded in Carbon Nanotubes(2019) Prischepa, S. L.; Danilyuk, A. L.; Kukharev, A. V.; Cojocaru, C. S.; Kargin, N. I.; Прищепа, Сергей Леонидович; Каргин, Николай ИвановичIEEEWe report on the magnetic properties of an array of binary metal CoFe, CoNi and CoPt nanoparticles (NPs) embedded inside vertically-oriented carbon nanotubes (CNTs). Samples were synthesized by chemical vapor deposition activated by current discharge plasma and hot filaments. Assemblies of Co-based catalytic NPs have been preliminary formed on SiO2/Si substrates by sputtering of ultrathin films followed by reduction in a H2/NH3 mixture. As a result of the CNT growth, each CNT contained only one ferromagnet top-located NP. For all samples the easy axis of magnetization was oriented along the CNT axis. Using the obtained experimental data and the random anisotropy model, the magnetic parameters like the effective anisotropy constant, the contribution of dipole interaction, shape, magnetocrystalline and magnetoelastic anisotropy were estimated. It is shown that the latter contribution of anisotropy is decisive. From the obtained magnetoelasticity the stresses in NPs embedded inside CNTs were determined. Finally, the magnetization distribution in CoFe, CoNi and CoPt NPs was simulated considering the magnetoelastic contribution.
