Measurements of thermoelectric properties of a thermoelectric cooler

Energy Conversion and Management, 1983
Abstract The effective thermoelectric parameters of a single stage cooler were measured as a function of temperature and compared with those of the n and p type materials from which the thermoelements were prepared. The performance of the cooler was calculated by a computerized iterative process using measured parameters and compared with ...

Flexible Quasi‐Solid State Ionogels with Remarkable Seebeck Coefficient and High Thermoelectric Properties

Advanced Energy Materials, 2019
Thermoelectric materials can be used to harvest low‐grade heat that is otherwise dissipated to the environment. But the conventional thermoelectric materials that are semiconductors or semimetals, usually exhibit a Seebeck coefficient of much less than 1

Thermoelectric properties and microstructure of Mg3Sb2

Journal of Solid State Chemistry, 2006
Abstract Mg3Sb2 has been prepared by direct reaction of the elements. Powder X-ray diffraction, thermal gravimetric, differential scanning calorimetery, and microprobe data were obtained on hot pressed samples. Single phase samples of Mg3Sb2 were prepared and found to contain oxygen at the grain boundaries and to lose Mg and oxidize at temperatures ...

Thermoelectric properties of Bi2O2Se

Materials Chemistry and Physics, 2010
Abstract Bi 2 O 2 Se was synthesized from Bi 2 Se 3 and Bi 2 O 3 by solid state reaction in an evacuated quartz ampoule. The product crystallizes in the tetragonal type lattice and X-ray pattern displays lines of the Bi 2 O 2 Se only. Samples for thermoelectric property measurements were prepared using hot pressing in rectangular graphite dies. The

Thermoelectrical properties of superlattices

XVI ICT '97. Proceedings ICT'97. 16th International Conference on Thermoelectrics (Cat. No.97TH8291), 2002
Recent investigations show that thermoelectric properties of superlattices, where electronic density of states is two-dimensional, may be greatly improved. In our report the calculations of thermoelectric properties of Si/Ge superlattices are proposed. Superlattice band structure was calculated in the frame of the tight-binding model (sp/sup 3/s/sup */)

Thermoelectric properties of KCaF3

Physica B: Condensed Matter, 2019
Abstract Using first-principles calculations based on density functional theory (DFT) with generalized gradient approximation (GGA), the electronic and thermoelectric properties of KCaF3 are calculated. The electronic structure calculated with GGA shows that KCaF3 is an insulator.

Thermoelectric properties of CoSb3

Journal of Alloys and Compounds, 2001
Abstract The typical skutterudite structure compound CoSb 3 was prepared by arc melting followed by sintering. The samples were characterized by powder X-ray diffraction method, electron probe microanalysis (EPMA), and the thermoelectric properties such as the thermal diffusivity, electrical resistivity, and Seebeck coefficient were measured in the ...
