Master's Degree Programs

The department focuses on theoretical and experimental research in the field of high-efficient thermoelectric materials, nanocomposites included, for developing a new generation of cooling units and thermoelectric power generators. Introduction of these inventions will contribute to the decrease of the man-induced impact on the environment and utilization of thermal waste.

The department has completed such projects as development of the theory of transfer phenomena in bulk nanocrystalline thermoelectrics with regard to electron tunneling, theory of additional photon scattering, selective carrier scattering and phonon spectrum anisotropy, as well as methods to increase the efficiency of bulk nanocrystalline composites based on bismuth telluride by creating nanopowders using mechano-active processing followed by hot pressing or spark plasma sintering. The effectiveness of the preproduction prototypes created at the department is 25% higher than in the best counterparts.

A theory of a hybrid photo-thermoelectric solar generator has been proposed; its preproduction prototype has been manufactured and tested as part of an international project.

As of now, the following R&D projects are conducted by the department:

  • # 350884. Topic: Increasing the efficiency of thermoelectrics based on chalcogenides of bismuth and stibium by creating bulk nanostuctures with controlled properties;

  • # 14707. Topic: Development of methods for simulating the synthesis of nanothermoelectrics using spark plasma sintering;

  • # 350884. Topic: Creation of nanostructures based on germanium silicide and silicides of transition metals for thermoelectric generators;

  • # 713547. Topic: Functional  materials for thermoelectric generators and bulk coolers;

  • Research of the methods and design concepts of technogenic safety devices and systems.
