Thermoelectric systems: Ion beam enhanced thermoelectric properties

Applied Surface Science, 2014
Abstract A thermoelectric system based on the interaction of composites of two metal nanocrystals in silica substrate prepared by a multilayer structure having alternate layers of metal/material mixture is discussed in detail in this paper. The alternate layers component of this work has two metal content, gold and silver.

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 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 ...

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 pressure-sintered Si0.8Ge0.2 thermoelectric alloys

Journal of Applied Physics, 1991
The thermoelectric properties of 28 sintered Si0.8 Ge0.2 alloys, heavily doped with either boron or phosphorus and prepared from powders with median particle sizes ranging from about 1 μm to over 100 μm, have been determined from 300 to 1300 K. The thermal conductivity decreases with decreasing particle size, however, the figure of merit is not ...

Thermoelectric properties of Ag3AuTe2

Journal of Applied Physics, 2000
Electronic structure calculations predict Ag3AuTe2 to be a small-band-gap semiconductor. Polycrystalline samples of the pure and doped materials have been synthesized, and the physical properties are reported. Thermoelectric power measurements indicate that pure Ag3AuTe2 is a p-type material with a very large room-temperature Seebeck coefficient of 530

Thermoelectric Properties of Ag2Te

Journal of Applied Physics, 1961
The Seebeck coefficient α, electrical conductivity σ, and thermal conductivity K data are given for a number of Ag2Te specimens measured at room temperature. The maximum value observed for the figure of merit α2σ/K was 1.3×10−3°C−1. The relationship between K and σ was linear, and Kel could be expressed approximately by (π2/3) (k/e)2σT.

Thermoelectric properties of AgCrSe2

AIP Conference Proceedings, 2012
Temperature dependence of thermoelectric properties of AgCrSe2 has been studied from 300 K to 900 K. The thermopower (S) decreases initially and then increases with increasing temperature. The positive sign of S indicates that the compound is p-type thermoelectric material.

Thermoelectric properties of NaCo2O4

Journal of Alloys and Compounds, 2001
Abstract The thermoelectric properties such as the thermal conductivity, electrical resistivity and Seebeck coefficient of NaCo 2 O 4 and NaCo 1.9 M 0.1 O 4 (M=Ti, Rh, Pd) were evaluated in the temperature range from room temperature to 723 K. Polycrystalline samples were prepared by sintering in air followed by hot pressing.
