Promising Thermoelectric Materials for Terrestrial-Space Applications
Since the discovery of state-of-the-art thermoelectric materials in the 1960s, little improvement has been made in the thermoelectric material efficiency. Although numerous materials have been investigated for their thermoelectric properties, ZT value of 1 has not been significantly exceeded. This paper presents a new family of materials with the skutterudite crystal structure which, based on initial results obtained on several compounds of this family, has a good potential for thermoelectric applications. This class of materials covers a wide range of decomposition temperatures and bandgaps, which could be used for low, intermediate to high temperature applications.

Skutterudites: a New Class of Promising Thermoelectric Materials
Based on literature data and experimental findings at JPL, semiconductors with the skutterudite structure TPn(sub 3) (where T is a transition metal element such as Co, Rh, Ir, Ni and Pd, and Pn is a pnicogen element such as P, As and Sb) possess attractive characteristics and show a good potential for high ZT values. the high degree of covalency results in high mobility and low electrical resistivity values while a relatively complex 32-atom unit cell results in a reasonably low thermal conductivity.

Modeling of the Thermoelectric Properties of p-Type IrSb(sub 3)
IrSb(sub 3) is a compound of the skutterudite family of materials now being investigated at JPL. A combination of experimental and theoretical approaches has been recently applied at JPL to evaluate the potential of several thermoelectric materials such as n-type and p-type Si(sub 80) Ge(sub 20) alloys, n-type and p-type Bi(sub 2) Te(sub 3)-based alloys and p-type Ru(sub 2) Ge(sub 3) compound. The use of a comprehensive model for the thermal and electrical transport properties of a given material over its full temperature range of usefulness is a powerful tool for guiding experimental optimization of the composition, temperature and doping level as well as for predicting the maximum ZT value likely to be achieved.

Thermal Expansion and Some Properties ofCoSb(sub 3), RhSb(sub 3) and IrSb(sub 3)
IrSb3 and the isostructural compounds RhSb3 and CoSb3 were recently identified as new promising thermoetectric materials. The use of these materials in thermoelectric devices requires that their properties shall not change over long periods of time at operation temperature.
