An accurate and detailed theoretical model developed for n-type silicon-germanium (SiGe) indicates that ZT values several times higher than currently available are expected under certain conditions. These new, high ZT materials are expected to be significantly different from SiGe, but not unreasonably so. Several promising candidate materials have been identified which may meet the conditions required by theory. One such candidate, ruthenium silicide, currently under development at the Jet Propulsion Laboratory, has been estimated to have the potential to exhibit figure of merit values four times higher than conventional SiGe materials. Recent results are summarized.
