Аннотация:
The electrical resistivity of the SmxMn1−xS (0.15 ≤ x ≤ 0.25) solid solutions in the temperature range of 80–300 K was measured. Minimum and maximum in the temperature dependence of the resistivity were found, respectively, at T = 220 K for x = 0.15 and at T = 100 K for x = 0.2 compounds. This behavior is explained from the result of the mobility-edge movement, the disorder being due to elastic deformation and spin density fluctuations with short-range order. Metal–
semiconductor
phase transition versus concentration at xc = 0.25 is observed. Resistivity is described by scattering electrons with acoustic phonon mode and with localized manganese spin. From the thermal expansion coefficient the compression of the lattice below the Néel temperature for Sm0.2Mn0.8S is found.

Аннотация:
Pronounced optical- and bias-current-sensitive features of the transport properties of a Fe/SiO 2/p-Si hybrid structure in planar geometry at temperature variation are investigated. Comparative analysis of two Fe/SiO 2/p-Si samples, one with a continuous Fe film and the other with two electrodes formed from a Fe layer and separated by a micron gap, shows that these features are due to the MIS transition with a Schottky barrier near the interface between SiO 2 and p- Si. Resistance of such a MIS transition depends exponentially on temperature and bias. In the structure with a continuous ferromagnetic film, the competition between conductivities of the MIS transition and the Fe layer results in the effect of current channel switching between the Fe layer and a
semiconductor
substrate. Within certain limits, this process can be controlled by a bias current and optical radiation. The mechanism of the optical effect is photogeneration of electron-hole pairs in the
semiconductor
substrate near its boundary with SiO 2 layer. В© (2012) Trans Tech Publications.

Аннотация:
Pronounced magnetic-field- and bias-sensitive features of the transport properties of a Fe/SiO2/p-Si hybrid structure in planar geometry at temperature variation are investigated. Comparative analysis of two Fe/SiO 2/p-Si samples, one with a continuous Fe film and the other with two electrodes formed from a Fe layer and separated by a micron gap, shows that these features are due to the metal-insulator-
semiconductor
(MIS) transition with a Schottky barrier near the interface between SiO2 and p-Si. Resistance of such a MIS transition depends exponentially on temperature and bias. In the structure with a continuous ferromagnetic film, the competition between conductivities of the MIS transition and the Fe layer results in the effect of current channel switching between the Fe layer and a
semiconductor
substrate. Within certain limits, this process can be controlled by a bias current and a magnetic field. Positive magnetoresistance of the structures at high temperatures is determined, most likely, by disorder-induced weak localization. In the structure with the gap, negative magnetoresistance is observed at certain temperature and bias. Its occurrence should be attributed to an inversion layer formed in the
semiconductor
near the SiO2/p-Si interface when MIS transition is in the inversion regime. В© 2011 American Institute of Physics.

Аннотация:
We demonstrate that ferromagnetic metal/insulator/
semiconductor
hybrid structures represent a class of materials with the giant magnetoimpedance effect. In a metal-insulator-
semiconductor
diode with the Schottky barrier fabricated on the basis of the Fe/SiO2/n-Si structure, a drastic change in the impedance in an applied magnetic field was found. The maximum value of this effect was observed at temperatures of 10–30 K in the frequency range of 10 Hz–1 MHz where the ac magnetoresistance and magnetoreactance ratios exceeded 300% and 600%, respectively. In the low-frequency region (<1 kHz), these ratios could be controlled in wide range by applying bias to the device. The main contribution to the impedance when measured at temperatures corresponding to the strongest magnetic-field sensitivity comes from the interface states localized near the SiO2/n-Si interface and the processes of their recharging in an applied ac voltage. The applied magnetic field changes the energy structure of the interface states, thus affecting the processes of the charging dynamics.

Аннотация:
We have prepared thin indium oxide films by the autowave oxidation reaction. Measurements of temperature dependence of resistivity, Hall carrier concentration and Hall mobility have been conducted in the temperature range 5-272 K. Before ultraviolet (UV) irradiation, the indium oxide film had a
semiconductor
-like temperature dependence of resistivity. and the ratio of rho (5 K)/rho(272 K) was very limited (similar to 1.2). It was found that after UV irradiation of the In2O3 film, the metal-
semiconductor
transition (MST) was observed at similar to 100 K. To show that this MST is reversible and repeatable, two full cycles of 'absence of MST-presence of MST' have been done using UV irradiation (photoreduction) as the induced mechanism and exposure to an oxygen environment as the reversible mechanism, respectively. MST in transparent conducting oxide (TCO) is possibly associated with the undoped structure of metal oxide, which has some disorder of oxygen vacancies. It was suggested that reversible UV induced metal-
semiconductor
transition would occur in other TCOs.

Аннотация:
Results are presented of an experimental study of the temperature dependence of the electrical resistivity rho(T), critical current density J(c)(T), and current-voltage characteristics of polycrystalline composites based on the high-temperature superconductor Y3/4Lu1/4Ba2Cu3O7 and copper oxide with different lithium doping levels. The experimental temperature dependence of the critical current of composites with varying volume content of the
semiconductor
ingredient and varying charge carrier concentration are found to be in qualitative agreement with theory which takes account of Andreev reflection of the carriers at the S-Sm and Sm-S surfaces of the S-Sm-S Josephson junction (where S is the superconductor and Sm is the
semiconductor
). (C) 1997 American Institute of Physics.

Bulk Y3/4Lu1/4Ba2Cu3O7 + Cu1-xLixO composites with x = 0, 0.003 and 0.06 and varied volume content of Cu1-xLixO have been prepared. Analysis of the transport properties of the composites has shown that they can be represented as a network of superconductor-
semiconductor
-superconductor (S-Sm-S) weak links. The dependence of the critical current density on the normal resistance for the composites studied shows a behaviour similar to that for single Josephson junctions. The experimental temperature dependences of the critical current are qualitatively described in terms of a theory of S-Sm-S junctions that takes into account the Andreev reflection of carriers from the S-Sm and Sm-S interfaces.

Аннотация:
Results are presented of an experimental study of the temperature dependence of the electrical resistivity p(T), critical current density Jc(T), and current-voltage characteristics of polycrystalline composites based on the high-temperature superconductor Y3/4Lu1/4Ba2Cu3O7 and copper oxide with different lithium doping levels. The experimental temperature dependence of the critical current of composites with varying volume content of the
semiconductor
ingredient and varying charge carrier concentration are found to be in qualitative agreement with theory which takes account of Andreev reflection of the carriers at the S-Sm and Sm-S surfaces of the S-Sm-S Josephson junction (where S is the superconductor and Sm is the
semiconductor
). В© 1997 American Institute of Physics.

Аннотация:
The spectral properties of a one-dimensional photonic crystal with a defect nanocomposite layer that consists of metallic nanoballs distributed in a transparent matrix and is characterized by an effective resonance permittivity are studied. The problem of calculating the transmission, reflection, and absorption spectra of p-polarized waves in such structures is solved for oblique incidence of light, and the spectral manifestation of defect-mode splitting as a function of the volume fraction of nanoballs and the structural parameters is studied. The splitting is found to depend substantially on the nanoball concentration in the defect, the defect layer thickness, and the angle of incidence. The angle of incidence is found at which the resonance frequency of the nanocomposite is located near the edge of the bandgap or falls in the frequency region of a continuous spectrum. The resonance situation appearing in this case results in an additional transmission band or an additional bandgap in the transmission spectrum.

Аннотация:
The features of spatial and temporal evolution of two short laser pulses propagating in three-level medium under conditions of coherent population trapping and adiabatic population transfer is investigated in adiabatic approximation. It is shown that in both cases pulses can penetrate into a medium at a distance considerably exceeding the length of linear absorption of a single weak probe pulse in absence of a coupling pulse at adjacent transition. The difference of spatial and temporal evolution of level populations in processes of coherent population trapping and adiabatic population transfer is demonstrated. Also we show that the concept of dressed-field pulses is consequence of Manley-Raw relation.

Аннотация:
Single-crystalline MgFeBO4, Mg0.5Co0.5FeBO4, and CoFeBO4 have been grown by the flux method. The samples have been characterized by X-ray spectral analysis, X-ray diffraction, and X-ray absorption spectroscopy. The X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) spectra have been measured at the Fe and Co K-edges over a wide temperature range (6.5– 300 K). The composition, the charge state, and local environ- ment of both Fe and Co atoms have been determined. The effects of Co substitution for Mg on the local structural distortions have been revealed experimentally and the M–O bond anisotropy has been found.
Монокристаллические образцы CoFeBO4 были выращены раствор-расплавным методом. Образцы были охарактеризованы с помощью рентгеноспектрального анализа, рентгеновской дифракции и спектроскопии поглощения рентгеновских лучей. Спектры вблизи K-края поглощения рентгеновского излучения структуры (XANES) и далее рентгеновского поглощения тонкой структуры (EXAFS) были измерены для Fe и Co в широком диапазоне температур (6.5- 300К). Состав, состояние заряда, и локальная положение и Fe и Co атомов были определены. Эффекты замещения Co магнием Mg на местные структурные искажения были выявлены экспериментально и анизотропия связи М-О была найдена.
