Dispersion properties of inhomogeneous nanostructures.

We analyze the dispersive properties of inhomogeneous nanostructures (INSs) composed of alternating layers of different materials. Analysis of the interaction between the propagating pulse and the INS provides modified dispersion characteristics. An approximate theoretical model predicting the dispersion properties of the INS is developed and compared with more accurate numeric computation resu...

Thermal Properties of Semiconductor Low-Dimensional Structures

In this paper we review our work on thermal and thermoelectric properties of semiconductor low-dimensional structures, e.g. quantum wells and quantum wires, with emphasis on the effects of spatial confinement of acoustic phonons. We particularly concentrate on calculation of the phonon relaxation rates in mass-difference, Umklapp, point defect, and dislocation scattering processes that takes in...
