Isomorphic impurity effect on dielectric and nonlinear optical properties of (NH4)2SO4 / I. S. Kabanov, L. I. Zherebtsova, A. N. Vtyurin, V. F. Shabanov // Phys. Status Solidi A. - 1980. - Vol. 59, Is. 2. - P. 707-711, DOI 10.1002/pssa.2210590237. - Cited References: 7 . - ISSN 0031-8965
Аннотация: The temperature dependences are measured of spontaneous polarization and generation of optical second harmonics of ((NH4)1 − xRbx)2SO4 single crystals for x = 0.03. New components are found of the vector of spontaneous polarization and of the tensor of the nonlinear dielectric response. The results are explained by the different character of the compounds, containing NHurn:x-wiley:00318965:media:PSSA2210590237:tex2gif-stack-1- and Rb+-ions in the lattice and nonuniform distribution of impurities.

NOVEL MECHANISM FOR THE FORMATION OF IMPURITY LEVELS IN SEMICONDUCTORS WITH THE STRONG ELECTRON CORRELATIONS / S. G. OVCHINNIKOV // Zhurnal Eksperimentalnoi Teor. Fiz. - 1992. - Vol. 102, Is. 2. - P. 534-540. - Cited References: 8 . - ISSN 0044-4510

РУБ Physics, Multidisciplinary

Аннотация: In the framework of the generalized tight binding method involving the strong electron correlations it is shown that in spite of the lattice regularity the impurity-like localized levels may arise within the semiconducting gap with the deviation of the electron concentration from the integer value. The appearance of these levels is due to the contribution of multi-electron excited terms into the single-particle density of states.

POLARIZED LUMINESCENCE SPECTRUM OF IMPURITY LIQUID-CRYSTAL - THE DEGENERATION LIFTED AND RENEWED BY RELAXATION / E. M. AVERYANOV // Zhurnal Eksperimentalnoi Teor. Fiz. - 1993. - Vol. 103, Is. 6. - P. 2018-2038. - Cited References: 45 . - ISSN 0044-4510

Аннотация: The general molecular-statistical approach is proposed for the analysis or the polarized luminescence spectrum for impurity molecule of an arbitrary symmetry in the nematic liquid crystal matrix. On the particular example of uniaxial molecules the influence of features of the molecular electron structure, orientational statistics, molecular dynamics, and features of the anisotropic intermolecular coupling upon the positions of maxima v(if)(t) of impurity fluorescence polarized bands J(ij)(t) is studied. For the first time it is shown that all these factors significantly affect the degree of spectrum v(ij)(t) degeneration. For t not-equal 0, relaxation of excited impurity molecule subsystem toward the orientational distribution lifts a partial degeneration of spectrum v(ij), occuring at t not-equal 0, and renews partial or total degeneration of spectrum v(ij) in the limit t = infinity. In the lack of the spectrum v(ij) degeneration for t = 0 the relaxation may restore partial degeneration for t not-equal 0 as a function of the features of electron structure of molecules. The results of work explain the familiar experimental data on the number of independent component v(ij) and relation between them, on dependence of v(ij) upon the order of matrix and impurity subsystem, on the mutual relation in the positions of impurity band polarized component in the absorption and fluorescence spectra.

Аннотация: A new approach is proposed for interpreting the polarized fluorescence spectra of an impure liquid crystal in which the orientational order of excited impurity molecules has undergone relaxation. This approach has also been realized experimentally. The new experimental data demonstrate a new relaxation process with a time scale on the order of 10(-11)-10(-9) s.

Аннотация: A difference is predicted between the peaks, nu(VV) and nu(VH), Of the polarized components J(VV)(nu) and J(VH)(nu) in the steady-state spectrum of impurity fluorescence in an isotropic solution. This difference would result from a temporal correlation between an orientational Brownian diffusion of excited fluorescing molecules and a structural relaxation of the surrounding matrix molecules.

manganese perovskites -- mobility -- linear and quadratic magnetoresistance
Аннотация: We present a two-time of relaxation approach at an analysis of a magnetoresistance in ferromagnetic manganese perovskites La(1-x)(Ca,Sr)(x)MnO. To explain a change in the low-held response from predominantly quadratic dR/dH\(H-->0) = 0 for T > T(c) to linear dR/dH\(H-->0) for T < T(c) as noted in the measurements in thin films La(0.7)Ca(0.3)MnO(3) we calculated held and temperature dependences of a impurity contribution to a carrier mobility in a framework of the 2p(O)- and 3d(Mn)-scattering model elaborated for manganese perovskites. We obtained the field-dependent impurity contribution to the overall scattering of carriers that show a transition in the low-field (H) dependence of R from quadratic above T(c) to linear below consistent with an experiment. The calculated negative magnetoresistance ratio is sharply peaked at a temperature-near T(c) or below. (C) 1999 Elsevier Science B.V. All rights reserved.

Аннотация: By means of a diagram technique for Hubbard operators, we show the existence of a spin-dependent renormalization of the localized levels in an interacting region, e.g., quantum dot, modeled by the Anderson Hamiltonian with two conduction bands. It is shown that the renormalization of the levels with a given spin direction is due to kinematic interactions with the conduction subbands of the opposite spin. The consequence of this dressing of the localized levels is a drastically decreased tunneling current for ferromagnetically ordered leads compared to that of paramagnetically ordered leads. Furthermore, the studied system shows a spin-dependent resonant tunneling behavior for ferromagnetically ordered leads.

Аннотация: Three issues are analyzed in the physics of time-dependent tunneling current through a quantum dot with strongly correlated electrons coupled to two external contact leads: (i) nonorthogonality of the states of electrons in the leads and in the quantum dot, (ii) non-Fermi statistics of the excitations in the quantum dot, and iii) kinematic shift of the quantum dot levels. The contributions from nonorthogonality effectively decrease the mixing interaction between the leads and the quantum dot and the width of the quantum dot level whereas the Gibbs statistics slightly changes the spectral weights of quantum dot levels, and decreases the widths, but does not introduce drastical changes to the current. The kinematic interactions are taken into account within the loop correction. For the case of block signal, the time-dependent current shows oscillations starting at the onset and termination of the bias voltage pulse.

Аннотация: The polarized electronic absorption spectra, orientation ordering, and the special local field features were studied for push-pull linear dye molecules with strong donor-acceptor electronic conjugation of terminal fragments in the matrix of a nematic liquid crystal. The temperature-induced inversion of the sign of the splitting of polarized impurity absorption bands was observed. This effect was shown to be caused by the statistical character of orientation ordering of impurity molecules and manifestation of the higher moments of the orientation distribution function. The dependence of local field parameters (Lorentz tensor components) of impurity molecules on their orientation ordering was established. This dependence was used to reproduce the temperature dependence of the orientation order parameter of the matrix. (C) 2004 MAIK "Nauka / Interperiodica".
