Analytical expressions for Seebeck and Peltier coefficients in semiconductor nanostructures of different geometries with nonequilibrium charge carriers are obtained. It is shown that the nonequilibrium distribution function of electrons in metal contacts contributes to the kinetic coefficients in the linear approximation. The change of theoretical power limit and thermal energy converter efficiency due to nonequilibrium are derived. The thermoelectric effect in systems with neglectable drift electric current is predicted. 2. The electronic transport in a bilayered system of two-dimensional conductors in an external dc magnetic field is studied. The dispersion relation for acoustic, optical, magnetoviscous, and magnetothermal plasmons is obtained. An analytical expression for the magnetodrag is derived. Its dependence on the magnetic field is nonmonotonic and sensitive to the values of quantum coefficients of Seebeck and Peltier and quantum conductivity. 3. The Aharonov–Bohm effect in semiconductor nanotube with dielectric filling is studied. The spectrum of the eigenmodes is obtained taking into account the effect of retardation. The Aharonov–Bohm effect manifests itself as the appearance of periodic changes in frequencies of eigenmodes of the structure on the magnitude of magnetic flux. 4. A method for calculating the leaking field at arbitrary intensity of electromagnetic scattering on the randomly rough metal-dielectric interface have been developed. It is shown that direction of the leaking field can be artificially changed from almost diffuse to extremely anisotropic, depending on the statistical parameters of the inhomogeneous interface area and the Anderson localization. It is shown that the main parameter determining the intensity of the plasmon-polariton wave scattering is the roughness sharpening of the interface rather than the amplitude of surface fluctuation Product Description popup.authors Apostolov Stanislav S.
