Today, known thermoelectric thin-film micromodules operating at room temperatures use antimony and bismuth tellurides (compounds V-VI) as working materials. However, recent studies show that the modification of vapor-phase technologies for the deposition of materials based on compounds IV-VI with impurities in the cationic or anionic sublattice can increase the quality factor of the material: lower thermal conductivity by creating numerous grain boundaries and increasing the thermo-EMF coefficient Fermi level. This will result in obtaining thermoelectric efficiency values ​​of such materials at the level of the same values ​​as for bismuth telluride, but at the same time significantly expand the range of their practical use using significantly cheaper technologies: instead of (250-350) K for Bi2Te3 to (300-800) K for the case of PbTe-based materials. All this will lead to a more universal application of the thermoelectric module, and the use of vapor-phase technologies, in addition, will reduce its cost.
