Polycrystalline p‐type samples of IrSb3 and Ir0.5Rh0.5Sb3 have been made by hot isostatic pressing of powders. A number of properties such as thermal expansion coefficient, sound velocity, thermal conductivity, electrical conductivity, Seebeck coefficient, and carrier concentration have been measured. These compounds show promise as thermoelectric materials.read more

Filled Skutterudite Antimonides: A New Class of Thermoelectric Materials
TL;DR: A class of thermoelectric materials has been synthesized with a thermoeLECTric figure of merit ZT near 1 at 800 kelvin, which is comparable to the best ZT values obtained for any previously studied thermOElectric material.

SKUTTERUDITES : A phonon-glass-electron crystal approach to advanced thermoelectric energy conversion applications
TL;DR: In this paper, the authors proposed a method to compare one potential thermoelectric material with another, based on a numerical expression that is commonly used to compare the performance or efficiency of a particular device made from a material.
Journal ArticleDOI
Thermoelectric Materials: New Approaches to an Old Problem
TL;DR: In this paper, it was shown that passing an electric current through the junction in one direction caused the water to freeze, and reversing the current caused the ice to quickly melt; thus thermoelectric refrigeration was demonstrated.

The maximum possible conversion efficiency of silicon‐germanium thermoelectric generators
Glen A. Slack,Moayyed A. Hussain +1 more
TL;DR: In this paper, a model employing one valence band and two conduction bands has been used and detailed calculations for the efficiency of a thermoelectric generator made from a 70% Si-30% Ge alloy have been made over the temperature range from 300 to 1300 K. The utility/futility of GaP additions and grain boundary scattering as methods to increase the efficiency is discussed.
