T. Huber, A. Nikolaeva, D. Gitsu, L. Konopko, M.J. Graf, J. Huang. Thermoelectric Power of Bi AND Bi-Te (0.14%) In Porous Vycor Glass. P. 5-12.
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 semiconducting behavior of the resistance and very large enhancements of the thermoelectric power of composites containing Bi nanowires with diameters of 9 and 15 nm, we find that the resistance is not thermally activated and that the composites' thermoelectric power is of the same order of magnitude as the thermoelectric power of bulk Bi. Our results are consistent with the nanowires having carrier density that is enhanced by surface effects.

The new thermoelectric device - short-circuit semiconductor thermoelectric engine, which transforms low potential thermal energy into mechanical is presented. The principle of the work of the engine is in simultaneous use of Seebeck and Ampere effects. The engine may be used as a mechanical drive in autonomous energetic systems, and in those places where the need in energy can not be satisfied with conventional sources. Power, electromagnetic moment. rotational frequency of the rotor, and efficiency were calculated. The capability of operation of the device in modes of heat pump and cooler is shown. Except for energetic applying the engine can be used to produce autonomous thermal energy meters.

Investigation of thermoelectric coefficient and electrical resistivity was conducted on the same samples of eleven fusions of tungsten steels and carbon steel U10A in the state following normalizing annealing and in hardened steel. The tungsten and carbon content effect on the examined characteristics were analyzed. Higher concentration and structural sensitivity of thermoelectric properties of the investigated systems as compared to resistometric ones was observed. The findings can be applied for the assessment of surface decarbonization of components made of the above mentioned steels and for the analysis of phase-structural states.

G.Kavei, F.K. Aleskerov, K. Sh.Kahramanov and A.Kazemzadeh. Thermoelectric Characteristics Of Bi₂Te₃-In₂Se₃ Solid Solution Using CdCl₂ As Dopant. P.43-47.
Bi₂Te₃-In₂Se₃ crystals containing up to 5 mole% In₂Se₃ have been prepared by the melting-zone method. The crystallization process is accompanied with the substitution of In for Bi and Se for Te atoms in the Bi₂Te₃ lattice. It has been observed that such a substitution results in a significant drop of the thermal conductivity. This phenomenon has been attributed to vacancy defects occurred during the substitution process. Increasing the content of In₂Se₃ up to 3 mole% in the Bi₂Te₃-In₂Se₃ system alters the thermoelectric character from p-type to n-type. Exploring in the rang up to 5 mole% In₂Se₃ with different amount of CdCl₂ dopant at 300K, we have concluded that for 0.4-0.8 mole% In₂Se₃ and addition of 0.08 weight % CdCl₂ to the solid solution of Bi₂Te₃-In₂Se₃ give the figure of merit Z in the range of (2.63-2.74) 10^-3K^-1.

Ultrasound pulse method has been used to determine diagonal tensor components for elastic constants C_ijkl of Bi₂Te₃ based materials doped with isovalence impurities. The values C_ijkl have been used to study mechanical stresses generated in thermoelectric cooling modules during thermal cycling, as well as to establish the limits for elastic and plastic deformation. With the aim to increase cyclic stability of modules, computer design programs and experimental techniques for cyclic testing of modules have been developed. The test results have proved particularly high cyclic stability of modules manufactured of the above mentioned materials.

The influence of cooling on characteristics and parameters of semiconductor detectors based on CdTe and solid solution Cd_1-xZn_xTe has been studied. Electrical noise components, their dependences on the temperature (240-360 К) and ionizing radiation quantum energy (3 keV - 1 МeV) have been analyzed. It has been shown that the temperature reduction in the detector increases signal-to-noise ratio especially at registration of low-energy quantums, although cooling below 290-295 К proves to be inefficient. At the maximum ambient temperature +70°С the detector operating temperature 290-295 К is ensured by thermoelectric module whose electrical power requirement is 7 times less as compared to commercially available detectors of this type.
