    Влияние фотонной обработки и температуры на проводимость In2O3 пленок, полученных автоволновым окислением / И. А. Тамбасов [и др.] // Вестник СибГАУ. - 2013. - № 3. - С. 103-106. - Работа выполнена частично при финансовой поддержке ФЦП «Исследования и разработки по приоритетным направлениям развития научно-технологичного комплекса России на 2007-2013 годы» (госконтракт № 14.513.11.0023), а также Министерства образования и науки Российской Федерации (договор № 02.G25.31.0043) . - ISSN 1816-9724

Аннотация: Пленки оксида индия были синтезированы автоволновой реакцией окисления на покровном стекле, кварце и монокристалле MgO. Толщина пленки измерялась с помощью режима «cross-section» сканирующего электронного микроскопа и составляла ~300 нм. Оптическая ширина запрещенной зоны оксида индия была ~3.5 эВ. Исследования сопротивления In2O3 пленки от температуры в теневых условиях показали, что при нагревании до 100 0С сопротивление увеличивается на ~10 %. Показано, что при фотооблучении происходит резкое уменьшение электрического сопротивления пленок, максимальное изменение которого составило 52 % при комнатной температуре. Определены две скорости релаксации сопротивления пленок после прекращения облучения 15 Ом/сек первые 30 сек и 7 Ом/сек в остальное время. Сделано предположение, что фотовосстановление является доминирующим механизмом, ответственным за изменения проводимости пленок.
Indium oxide films were synthesized by auto-wave oxidation reaction on the cover glass, quartz and single crystal MgO. The film thickness was measured with a mode «cross-section» scanning electron microscope and was ~ 300 nm. Optical band gap of indium oxide was ~3.5 eV. The study of In2O3 film resistance versus temperature in the dark conditions showed that when heated to 100 °C the resistance increases by about 10 %. It is shown that the_ films electric resistance decreases sharply under photo radiation and the maximum change was 52 % at room temperature. The two film resistance relaxation rates after irradiation have been determined to be 15 Ohm/s the first 30 seconds and 7 Оhm/s f for the rest, respectively. On the basis of the above stated the authors suggest that the photo reduction is the dominant mechanism responsible for the changes in conductivity of In 2O 3 films.

Аннотация: In this paper, we study the effect of the layered structure of the active topsoil of the Arctic tundra during freezing on the error of determining surface deformation. A simple Bragg scattering model was used for surface scattering modeling. The simulation was performed in the L-band for future radar missions SMAP and ALOS-2. The soil permittivity is calculated using the temperature-dependent generalized refractive mixing dielectric model for the organic rich soil sample collected in North Slope, Alaska (68 degrees 38'N, 149 degrees 35'W). This model predicts the complex dielectric constant of moist soil both thawed and frozen at temperatures from -30 degrees C to +25 degrees C and moistures from 0 to 0.94 g/g. It is shown that the error of determining soil surface deformation, induced by processes of freezing of the permafrost active layer, does not exceed 1.5 cm.

Granular superconductor -- Josephson medium -- Effective field -- Magnetoresistance -- Magnetization hysteresis
Аннотация: The correlation between experimental magnetic field dependences of magnetoresistance and magnetization hysteresis in granular YBa2Cu3O7 is established. Within the proposed approach, magnetoresistance is assumed to be determined by the effective field in the intergrain boundaries the ensemble of which is considered to be a Josephson medium. The effective field in the intergrain medium can be written in the form B (eff)(H)=H-4 pi M(H)x alpha, where alpha is the parameter of averaged demagnetizing factors of grains and the degree of flux compression. A comparison of experimental magnetoresistance R(H) and magnetization M(H) hysteresis dependences obtained at different external magnetic field sweep rates yields the value alpha similar to 10, which is caused by the flux compression between grains. The proposed model describes well most of the features of the magnetoresistance hysteresis in granular high-T (C) superconductors.

Аннотация: We analyze how the magnetic disorder affects the properties of the two-band s± and s++ models, which are the subject of discussions regarding iron-based superconductors and other multiband systems like MgB2. We show that there are several cases when the transition temperature Tc is not fully suppressed by magnetic impurities in contrast to the Abrikosov-Gor'kov theory, but a saturation of Tc takes place in the regime of strong disorder. These cases are: (1) the purely interband impurity scattering and (2) the unitary scattering limit. We show that in the former case the s± gap is preserved, while the s++ state transforms into the s± state with increasing magnetic disorder. For case (2), the gap structure remains intact.

Аннотация: Nuclear magnetic resonance (NMR) imaging results are presented for the comparative study of sedimentation of the polymethylmethacrylate colloidal suspensions with spherical particle diameters of 475, 350 and 255 nm. The time evolution of the particle volume fraction in the sedimenting system, velocity of the fluid/suspension interface, interface broadening, and sediment growth velocity are measured against the system concentration as well as the container geometry. Using the experimental data the hindered settling function is evaluated. The influence of the container geometry on the parameters defining the hindered settling function in different approaches is evaluated for the first time. The limiting value of the particle diameter is estimated at which the container geometry has no impact any longer. This effect can be explained by the microscale structure persisting at low Peclet numbers. In addition, the influence of the container geometry on interface broadening and sediment formation for different particle diameters and volume fractions is studied. Spontaneous sediment packing induced by a modified container geometry has been found. NMR imaging has proven to be a highly efficient research tool for studying sedimentation at low Peclet numbers.

Аннотация: We report on abrupt changes in dc resistance and impedance of a diode with the Schottky barrier based on the Mn/SiO2/p-Si structure in a magnetic field. It was observed that at low temperatures the dc and ac resistances of the device change by a factor of more than 106 with an increase in a magnetic field to 200 mT. The strong effect of the magnetic field is observed only above the threshold forward bias across the diode. The ratios between ac and dc magnetoresistances can be tuned from almost zero to 108% by varying the bias. To explain the diversity of magnetotransport phenomena observed in the Mn/SiO2/p-Si structure, it is necessary to attract several mechanisms, which possibly work in different regions of the structure. The anomalously strong magnetotransport effects are attributed to the magnetic-field-dependent impact ionization in the bulk of a Si substrate. At the same time, the conditions for this process are specified by structure composition, which, in turn, affects the current through each structure region. The effect of magnetic field attributed to suppression of impact ionization via two mechanisms leads to an increase in the carrier energy required for initiation of impact ionization. The first mechanism is related to displacement of acceptor levels toward higher energies relative to the top of the valence band and the other mechanism is associated with the Lorentz forces affecting carrier trajectories between scatterings events. The estimated contributions of these two mechanisms are similar. The proposed structure is a good candidate for application in CMOS technology-compatible magnetic- and electric-field sensors and switching devices.

Аннотация: The ground and excited states of the pheromone molecules produced by xylophagous insects (the bark beetle Ips typographus L., the black fir sawyer beetle Monochamus urussovi Fisch., and the black pine sawyer M. galloprovincialis Oliv.) were modeled using a quantum chemical method utilizing DFT (density functional theory) with the B3LYP functional. The absorption wavelengths (energies) and dipole moments were calculated; the transitions of electrons from occupied to empty molecular orbitals were considered. The computed data were used to assess the stability of pheromone molecules exposed to environmental factors, such as solar radiation and humidity.
