Frequency-Concentration Dependence of Optical Activity of a Non-Ideal 1D-Superlattice

Journal of Modern Physics 2011年第12期2卷 1574-1578页

作者： Vladimir V. Rumyantsev stanislav a fedorov 不详

In the present work the widths of layers constituting the non-ideal superlattice are much bigger then the characteristic scales of space dispersion. In such a case the contribution of individual layers to gyrotropy can be regarded as independed. Thus the corresponding optical quantities can be expressed through the layers’ gyrotropic characteristics. This approach is applied to calculate the specific rotation angle of plane of polarization of light propagating through a nonideal 1D-superlattice, which varies in composition as well as in layers’ width. We carry out numerical calculation of the frequency dispersion of optical activity of a non-ideal superlattice, which includes impurity layers with point defects.

Optical Rotation of Linearly Polarized Light Propagating through a Nonideal 1D-Superlattice

Materials Sciences and Applications 2010年第1期1卷 32-35页

作者： Vladimir V. Rumyantsev stanislav A. fedorov 不详

The problem of finding polariton modes (necessary for calculating gyrotropic characteristics) in space-dispersed superlattices is not yet solved. At the same time the specified quantities can be approximately evaluated if the widths of layers comprising a multilayer material are much bigger then the characteristic scales of space dispersion. In such a case the contribution of individual layers to gyrotropy can be regarded as independed. Thus the corresponding optical quantities can be expressed through the layers' gyrotropic characteristics. This approach is applied to calculate the specific rotation angle of plane of polarization of light propagating through a nonideal 1D-superlattice, which varies in composition as well as in layers' width.

Geometrical Modeling of Crystal Structures with Use of Space of Elliptic Riemannian Geometry

引用

Materials Sciences and Applications 2011年第6期2卷 526-536页

作者： stanislav Rudnev Boris Semukhin Andrey Klishin 不详

The space of internal geometry of a model of a real crystal is supposed to be finite, closed, and with a constant Gaussian curvature equal to unity, permitting the realization of lattice systems in accordance with fedorov groups of transformations. For visualizing computations, the interpretation of geometrical objects on a Clifford surface (SK) in Riemannian geometry with the help of a 2D torus in a Euclidean space is used. The F-algorithm ensures a computation of 2D sections of models of point systems arranged perpendicularly to the symmetry axes l3, l4, and l6. The results of modeling can be used for calculations of geometrical sizes of crystal structures, nanostructures, parameters of the cluster organization of oxides, as well as for the development of practical applications connected with improving the structural characteristics of crystalline materials.
