Thermoelectric figure of merit of quantum wire superlattices

Applied Physics Letters, 1995
The electrical conductivity, the thermoelectric power, and the electrical contribution to the thermal conductivity of quantum wire superlattices have been studied. The effects of tunneling through the barriers due to finite potential off-sets and of the thermal currents through the barrier layers are shown to be essential to describe properly the ...

Theoretical analysis of the thermoelectric figure of merit

Energy Conversion and Management, 1980
Abstract A theoretical analysis of the thermoelectric figure of merit is presented based upon a two band conduction model for single and many valley semiconductors. The figure of merit is obtained as a function of reduced Fermi potential for a model system which is a close approximation to the silicon-germanium alloys currently employed in ...

Thermoelectric figure of merit of LSCoO–Mn perovskites

Microelectronics Journal, 2008
Abstract Oxide ceramics with nominal composition of La 0.8 Sr 0.2 Co 1 - x Mn x O 3 ( 0 ⩽ x ⩽ 0.05 ) were grown by using the citrate sol–gel method followed by high temperature sintering. The thermoelectric properties were studied in the temperature range between 100 and 290 K.

High Figure Of Merit Thermoelectrics: Theoretical Considerations

Proceedings of the 25th Intersociety Energy Conversion Engineering Conference, 2005
The thermoelectric figure of merit of a semiconductor, ZT, can be calculated from a small number of microscopic material parameters, the material composition, the doping level, and the temperature. The functional dependence of ZT on these parameters has been studied for a range of material parameters using a recently developed model which accurately ...

On the Figure of Merit of Thermoelectric Generators

Journal of Energy Resources Technology, 2005
In order to improve the performance of semiconductor thermoelectric power generators, a high figure of merit Z of both material and generator system has been a target for a long time. In this technical brief, it is demonstrated that a higher value of Z does not always guarantee better generating performances because of the thermoelectric-coupled effect

Enhanced Thermoelectric Figure of Merit of p-Type Half-Heuslers

Nano Letters, 2011
Half-Heuslers would be important thermoelectric materials due to their high temperature stability and abundance if their dimensionless thermoelectric figure of merit (ZT) could be made high enough. The highest peak ZT of a p-type half-Heusler has been so far reported about 0.5 due to the high thermal conductivity. Through a nanocomposite approach using

Multi-heterojunctioned plastics with high thermoelectric figure of merit

Nature
Conjugated polymers promise inherently flexible and low-cost thermoelectrics for powering the Internet of Things from waste heat1,2. Their valuable applications, however, have been hitherto hindered by the low dimensionless figure of merit (ZT)3-6.

Extrapolated thermoelectric figure of merit of ruthenium silicide

AIP Conference Proceedings, 1992
Recently, single crystals have been grown of a promising new thermoelectric material, ruthenium silicide (Ru2Si3). Although high figure of merit values have not actually been achieved as yet, the intrinsic properties of Ru2Si3 appear to be very favorable for thermoelectric applications.

Load-Bearing Figure-of-Merit Characterization of a Thermoelectric Module

IEEE Transactions on Components, Packaging and Manufacturing Technology, 2016
Thermoelectric behavior in semiconductor materials is investigated for the purpose of converting thermal energy to electrical energy. This paper measures and quantifies the variations in the internal electrical and thermal resistances of a thermoelectric module with respect to the circuit’s electrical load in order to better characterize its behavior ...
