V.A. Semeniouk. Problems and Prospects of Multi-Stage Cooling
This paper discusses the limit possibilities to widen the temperature range of cascade thermoelectric coolers (TECs) using best modern thermoelectric materials. Factors which affect multi-stage TECs efficiency are considered. The best practical results of low temperature low power cascade TECs development are represented.
L.I.Anatychuk, O.J.Luste. Physical Principles of Microminiaturization in Thermoelectricity
Factors, which promote to microminiaturization of cooling modules have been considered. Results of thermoelectric coolers investigations are presented with taking into account all classical factors: electrical and heat resistance of a commutation, contact resistance, heat resistance of heat transfers, all kinds of thermoelectric effects, temperature dependencies of material properties, etc. The influence of all factors on cooling efficiency is analyzed. New factors, which can have influence on a module work, namely strong electric field, large temperature gradient, size effects, diffusion processes are considered. The influence on microminiaturization and conditions for these factors actions are analyzed. A common analysis for microminiaturization limits and a prognosis of thermoelectric modules development is presented.

The all-round investigation of thermoelectric coefficient, parallel with Young’s module, density, electrical resistivity, saturation magnetic induction of Fe-Ni-Mn alloys (N25G2, N21G4, N17G6, N13G8, N9G10) has been carried out in the two-phase martensite-austenite states formed by hardening and temperings. Using the results of similar measurements on basic binary Fe-Ni alloys it was shown that manganese has a peculiar effect on the electron structure of Fe-Ni matrix, and replacement of Ni atoms by manganese leads to the reduction of thermoelectric coefficient of alloys. Manganese causes greater reduction of thermoelectric coefficient of the alloys in j-state with face-centered cubic structure even at higher percentage of nickel. In its informativeness and sensitivity to such phase-structural
