Аннотация: The atomic structure and elastic properties of silicon carbide nanowires of different shapes and effective sizes were studied using density functional theory and classical molecular mechanics. Upon surface relaxation, surface reconstruction led to the splitting of the wire geometry, forming both hexagonal (surface) and cubic phases (bulk). The behavior of the pristine SiC wires under compression and stretching was studied and Young's moduli were obtained. For Y-shaped SiC nanowires the effective Young's moduli and behavior in inelastic regime were elucidated.

Аннотация: In SrxBa1-xNb2O6 crystals (x = 0.33, 0.5, 0.61, and 0.75), temperature dependences of spontaneous polarization, strain, elastic modules, and second harmonic generation (SHG) signal are compared. It is revealed that SHG describes the temperature dependences of dipole moments in polar nanoregions in paraelectric phase. In the vicinity of the phase transition in paraelectric phase, SHG reflects the temperature behavior of relatively large and long-lived polar asymmetric regions as indicated by the presence of the intermediate temperature range on the temperature dependence of this nonlinear response.

    Synthesis, structure and properties of K2(1-x)Rb2xAl2B2O7 and Cs1.39Tl0.61Al2B2O7 borates as the basis for preparing new oxide materials / V. G. Grossman [et al.] // Lett.

Аннотация: With the development of technology, the need for highly efficient functional materials is steadily increasing. Currently, borates attract the attention of researchers, as they are promising nonlinear materials. Potassium rubidium aluminum borate based on potassium aluminum borate (trigonal syngony, space group P321, Z = 3) was obtained by solid-phase synthesis. The individuality and purity of the borates were confirmed by X-ray diffraction. Analysis of differential scanning calorimetry and thermogravimetric method for K2(1‑x)Rb2xAl2B2O7 (x = 0.1– 0.8) was performed in the temperature range of 25–1075°С. Potassium rubidium borates decompose in the temperature range of 900 –1000°C. Differential scanning calorimetry, dielectric loss tangent, and second-harmonic generation data revealed phase transitions for K0.6Rb1.4Al2B2O7. A significant SHG effect was found at room temperature for K0.6Rb1.4Al2B2O7 (Q = 70). Then the SHG effect increases to Q = 85 at a temperature of 645°C and remains constant with a further increase in temperature. The new triple borate Cs1.39Tl0.61Al2B2O7 was synthesized by the solid-phase synthesis, and its crystallographic parameters were obtained by the Rietveld method. This borate crystallizes in the monoclinic space group P21 / c with the unit cell parameters: Z = 2, a = 6.6669(3) Å, b = 7.2991(3) Å , c = 9.3589(4) Å , β =116.6795(18)°, V = 406.94(3) Å 3. The structure can be considered to be built up from the nearly planar [Al2B2O10] rings, which are composed of two AlO4 tetrahedra and two BO3 triangles, connected, alternately to each other by corner-sharing.
С развитием технологии потребность в высокоэффективных функциональных материалах растет. В настоящее время бораты привлекают внимание исследователей, поскольку они являются перспективными нелинейными материалами. Твердофазным синтезом получены бораты K2(1-x)Rb2xAl2B2O7 (x = 0.1–0.8) на основе калий-алюминиевого бората (тригональная сингония, пространственная группа P321, Z = 3). Индивидуальность и чистота боратов подтверждена рентгеновской дифракцией. Анализ дифференциально-сканирующей калориметрией и термогравиметрическим методом для K2(1-x)Rb2xAl2B2O7 (x = 0.1–0.8) был проведен в интервале температур 25–1075 ºС. Калий-рубидиевые бораты разлагаются в интервале температур 900–1000 °C. Дифференциальной сканирующей калориметрией, диэлектрическими измерениями и методом генерации второй оптической гармоники выявлены фазовые переходы для K0.6Rb1.4Al2B2O7. Значительный ГВГ-эффект был обнаружен при комнатной температуре для K0.6Rb1.4Al2B2O7 (Q = 70). Эффект генерации второй гармоники возрастает до Q = 85 при температуре 645 °C и остается постоянным при дальнейшем увеличении температуры. Новый тройной борат Cs1.39Tl0.61Al2B2O7 был синтезирован методом твердофазного синтеза, а его кристаллографические параметры были получены с помощью метода Ритвельда. Этот борат кристаллизуется в моноклинной пространственной группе P21/c с параметрами элементарной ячейки: Z = 2, a = 6.6669 (3) Å, b = 7.2991 (3) Å, c = 9.3589 (4) Å, β = 116.6795 (18)º, V = 406.94 (3) Å3. Структуру можно представить в виде почти плоских колец [Al2B2O10], которые состоят из двух тетраэдров AlO4 и двух BO3 треугольников, соединенных попеременно друг с другом посредством вершин.

Аннотация: Silicon carbide 6H-SiC nanoparticles and nanowires were obtained in carbon-silicon high-frequency arc plasma plasma in a helium atmosphere at a pressure of 0.1-0.6 MPa. It was shown that 6H-SiC nanowires grow from the arc plasma, as well as from the vapor, according to the known mechanism of vapor-solid condensation on a cold surface covered with single-crystal silicon carbide nuclei. The content of silicon carbide nanowires in the condensate reached 60 wt %. The obtained single-crystal silicon 6H-SiC nanowires had the diameter of 15-18 nm and length of 200-600 nm.

Аннотация: Structure and optical properties of new nonlinear crystal - Li2Ga2GeS6 single crystal of optical quality, grown by the Bridgman technique were studied. The data on transmission, Raman scattering, luminescence emission, excitation and thermal quenching as well as thermostimulated luminescence are presented. Fundamental absorption edge is determined by the direct allowed electronic transitions: The values of optical band gap are estimated. Absorption band at 8.0 mu m is due to S-S vibrations. Features in photoluminescence spectra are associated with excitons: both free (narrow line at 371 nm) and self-trapped ones (broad bands at 596, 730 and 906 nm). Spontaneous emission in the 80-170 K range, both at crystal heating and cooling, is typical of pyroelectrics: This confirms the absence of symmetry center in Li2Ga2GeS6 and an opportunity of laser frequency nonlinear conversion.

Аннотация: The optical properties and structure of gadolinium iron borate GdFe3(BO3)(4) crystals are studied at high pressures produced in diamond-anvil cells. X-ray diffraction data obtained at a pressure of 25.6 GPa reveal a first-order phase transition retaining the trigonal symmetry and increasing the unit cell volume by 8%. The equation of state is obtained and the compressibility of the crystal is estimated before and after the phase transition. The optical spectra reveal two electronic transitions at pressures similar to26 GPa and similar to43 GPa. Upon the first transition, the optical gap decreases jumpwise from 3.1 to similar to2.25 eV. Upon the second transition at P = 43 GPa, the optical gap deceases down to similar to0.7 eV, demonstrating a dielectric-semiconductor transition. By using the theoretical model developed for a FeBO3 crystal and taking into account some structural analogs of these materials, the anomalies of the high-pressure optical spectra are explained.

Аннотация: Magnetic properties of GdFe3(BO3)(4) single crystals were investigated by Fe-57-Mossbauer spectroscopy and static magnetic measurements. In the ground state, the GdFe3(BO3)(4) crystal is an easy-axis compensated antiferromagnet, but the easy axis of iron moments does not coincide with the crystal C-3 axis, deviating from it by about 20 degrees. The spontaneous and field-induced spin reorientation effects were observed and studied in detail. The specific directions of iron magnetic moments were determined for different temperatures and applied fields. Large values of the angle between the Fe3+ magnetic moments and the C-3 axis in the easy-axis phase and between Fe3+ moments and the a(2) axis in the easy-plane phase reveal the tilted antiferromagnetic structure.

Аннотация: Absorption spectra of the Nd3+ ions in an orthorhombic δ-BiB3O6 single crystal were measured in the spectral range 11,000-20,500 cm-1. The f-f transition intensities were analyzed in terms of the Judd-Ofelt theory, and the following parameters of the theory were obtained: Ω2 = 6.35 × 10-20 cm2, Ω4 = 4.86 × 10-20 cm 2, and Ω6 = 11.233 × 10-20 cm 2. The strengths, spontaneous emission probabilities, branching ratios, spectroscopic quality factor and excited state radiative lifetime were calculated for laser transitions from the 4F3/2 state to 4IJ manifold. Spectroscopic properties of Nd 3+:δ-BiB3O6 crystal favor lasing at 1.3 μm, where this crystal possesses near non-critical phase matching for second harmonic generation. © 2012 Elsevier B.V.

Аннотация: Single crystal of ErAl3(BO3)4 was grown and its structure was studied. Polarized absorption spectra of ErAl3(BO3)4 single crystal were measured in the spectral range 1670–330 nm (6000–30000 cm−1). The Judd–Ofelt spectroscopic parameters have been determined: Ω2 = 4.87 × 10−20 cm2, Ω4 = 2.49 × 10−20 cm2, Ω6 = 2.72 × 10−20 cm2. These parameters have been used to calculate the radiative transition probabilities, the multiplet luminescence branching ratios and the fluorescence life times of the manifolds. The luminescence spectra due to transitions 2H11/2 → 4I15/2 (526 nm), 4S3/2 → 4I15/2 (548 nm), 4F9/2 → 4I15/2 (662 nm), 2H11/2 → 4I13/2 + 4I9/2 → 4I15/2 (800 nm) and 4S3/2 → 4I13/2 (855 nm) were recorded in α, σ and π polarizations. The most intensive luminescence belonged to 4S3/2 → 4I15/2 transition (548 nm).
Поляризованные спектры поглощения ErAl3 (BO3) 4 монокристалла были измерены в спектральном диапазоне 1670-330 нм (6000-30000 см-1). Спектроскопические параметры Джадда-Офельта были определены как: Ω2 = 4,87 • 10-20 см2, Ω4 = 2.49 • 10-20 см2, Ω6 = 2,72 • 10-20 см2. Параметры были использованы для расчета вероятностей излучающих переходов, мультиплетные отношения люминесценции раскола и времена жизни мультиплетов. Спектры люминесценции за счет переходов 2П11 / 2 → 4I15 / 2 (526 нм), 4S3 / 2 → 4I15 / 2 (548 нм), 4F9 / 2 → 4I15 / 2 (662 нм), 2П11 / 2 → 4I13 / 2 + 4I9 / 2 → 4I15 / 2 (800 нм) и 4S3 / 2 → 4I13 / 2 (855 нм) были записаны в α, σ и π поляризации. Наиболее интенсивное свечение принадлежало переходу 4S3 / 2 → 4I15 / 2 (548 нм).

Аннотация: Solid-phase synthesis of solid solutions in the epitaxial Cu/Ni(001) bilayer film systems of compositions 3Cu: 1Ni, 1Cu: 1Ni, and 1Cu: 3Ni has been studied using the X-ray diffraction methods. The saturation magnetization and the magnetic crystallographic anisotropy constant on nickel vary in accordance with the solid solution formation. The initiation temperature of the solid solutions is about 350 A degrees C and is independent of the Ni: Cu layer thickness ratio. The solid-phase synthesis of the solid solutions is presumably attributed to the transport of the Cu atoms to the epitaxial Ni(001) layer. It is found that the solid-phase synthesis in the Cu/Ni bilayer nanofilms and multilayers is determined by the spinodal decomposition in the Cu-Ni system.

Аннотация: The solid-phase synthesis of manganese silicides on the Si(100)2 × 1 surface coated at room temperature by a 2-nm-thick manganese film has been investigated using high-energy-resolution photoelectron spectroscopy with synchrotron radiation. The dynamics of variation of the phase composition and electronic structure of the near-surface region with increasing sample annealing temperature to 600°C, has been revealed. It has been shown that, under these conditions, a solid solution of silicon in manganese, metallic manganese monosilicide MnSi, and semiconductor silicide MnSi1.7 are successively formed on the silicon surface. The films of both silicides are not continuous, with the fraction of the substrate surface occupied by them decreasing with increasing annealing temperature. The binding energies of the Si 2p and Mn 3p electrons in the compounds synthesized have been determined.

Аннотация: The results of experimental studies of self-propagating high-temperature synthesis in double-layer Cu/Au thin-film systems are presented. It is shown that the synthesis initiation temperature for a Cu/Au film is determined by the order-disorder phase-transition temperature in the Cu-Au system. The order-disorder transition temperature for thin films is found to be lower than for the bulky samples. It is assumed that the temperatures of initiation of solid-phase reactions in thin films can be associated with the structural phase-transition temperatures. (C) 2000 MAIK "Nauka/Interperiodica".

Аннотация: A comparative analysis was carried out of the initiation temperatures of solid-phase reactions in bilayer solid films and the Kurnakov temperatures of the phases forming in the reaction products. It has been shown that in superstructures where ordering is usually observed, the Kurnakov temperature coincides with the initiation temperature of the solid-phase reactions if no other solid-phase structural transformation precedes the order-disorder phase transition in the state diagram. A rule was proposed by which pairs of films capable of entering into solid-phase reactions and their initiation temperatures can be determined. (C) 2001 MAIK "Nauka/Interperiodica".

Аннотация: The self-propagating high-temperature synthesis in the two-layer and multilayer Pt / Co(001) thin films has been investigated. It is shown that the initiation of the synthesis occurs at temperatures of 770-820 K. After the synthesis in the two-layer film samples, the PtCo(001) disordered phase exhibits an epitaxial growth at the interface between cobalt and platinum layers. In the multilayer Pt/Co(001) thin films, the self-propagating high-temperature synthesis also brings about the formation of the PtCo(001) disordered phase on the MgO(001) surface. Further annealing at a temperature of 870 K for 4 h results in the transition of the PtCo(001) disordered phase to the ordered phase. Rapid thermal annealing of the Pt/Co(001) multilayer films at a temperature of 1000 K leads to the formation of the CoPt3 phase. The magnetic characteristics change in accord with the structural transformations in Pt/Co film samples. (C) 2000 MAIK "Nauka/Interperiodica".

Аннотация: Motivated by the experimental discovery of branched silicon nanowires, we performed theoretical electronic structure calculations of icosahedral silicon quantum dots embedded into pentagonal silicon nanowires. Using the semiempirical method, we studied the quantum confinement effect in the fully optimized embedded structures. It was found that (a) the band gaps of the embedded structures are closely related to the linear sizes of the longest constituting part rather than to the total linear dimension and (b) the discovered atypical quantum confinement with a plateau and a maximum can be attributed to the substantial interactions of near Fermi level electronic states of the quantum dots and nanowire segments.

Аннотация: A comparative study was performed of the low-temperature high-resolution absorption spectra of the Yb3+ probe in R1−xYbxAl3(BO3)4 (R = Y, Tm, Lu) crystals grown by flux technique independently in four different laboratories using different solvents. We show that the incorporation of solvent components into the crystal in the course of crystallization gives rise to spectral satellites of the Yb3+ 0(2F7/2) → 0′(2F5/2) absorption lines and assign particular satellites to the Yb3+ centers near the bismuth and molybdenum impurities (which decrease the transparency of YAB in the UV spectral range). We suggest this spectroscopic method for a rapid analysis of the quality of UV laser crystals and for improvement of growth technologies.

Аннотация: The Lu2.98Ce0.01Y0.01Al5O12 and Y2.99Ce0.01Al5O12 phosphors were synthesized by solid state reaction at temperature 1623 K and pressure 1.5 × 107 Pa in (95% N2 + 5% H2) atmosphere. Under the conditions, the compounds crystallize in the form of isolated euhedral partly faceted microcrystals ∼19 μm in size. The crystal structures of the Lu2.98Ce0.01Y0.01Al5O12 and Y2.99Ce0.01Al5O12 garnets have been obtained by Rietveld analysis. The photoluminescence (PL) and X-ray excited luminescence (XL) spectra obtained at room temperature indicate broad asymmetric bands with maxima near 519 and 540 nm for Y2.99Ce0.01Al5O12 and Lu2.98Ce0.01Y0.01Al5O12, respectively. The light source was fabricated using the powder Lu2.98Ce0.01Y0.01Al5O12 phosphor and commercial blue-emitting n-UV LED chips (λex = 450 nm). It is found that the CIE chromaticity coordinates are (x = 0.388, y = 0.563) with the warm white light emission correlated color temperature (CCT) of 6400 K and good luminous efficiency of 110 lm/W. © 2015 American Chemical Society.
