Physical concepts of building thermoelement models have been considered. Three basic approaches to creating thermoelement models are described. Comparative analysis of such approaches is made. Potential directions of thermoelectricity development are highlighted based on model concepts.
The difficulties of comparison between the experimental data and the results of theoretical description of nano-sized structures in the context of the band theory of solids were analyzed. A search for the ways to enhance the quality of nano-sized structures of the superlattice, quantum wire and quantum dot type were discussed as applied to the needs of thermoelectric thermal into electric energy conversion in the field of the so-called small-scale power engineering.
The main regularity of a thermodynamics of systems far from an equilibrium, processes of self-organizing in systems of a various type in these conditions surveyed. On the basis of the analysis of processes in plasma of stars, atmospheres of planets, depths of the Earth, plasma solid state at presence of a lapse rate of temperature the outputs about thermoelectric phenomenas in the self-organized heterogeneous structured are made is strongly nonequilibrium conditions at presence of a gradient of temperature. The offered approach does a science about thermoelectric phenomenas by one of funda
Semiconductor quantum wires constitute a promising thermoelectric material because of the increase of the electronic density of states in low-dimensional materials. We studied the magnetic-field-dependent resistance and Seebeck coefficient of a high-density network of 6-nm-diameter wires of Bi and of Bi doped with 0.14% component of Te embedded in porous Vycor glass. The resistance R increases as temperature decreases from 300 K down to 0.3 K for both composites. However, in contrast to recent results that demonstrate the sem
