RESEARCH PROGRAM ON SEMICONDUCTING COMPOUNDS FOR THERMOELECTRIC POWER GENERATION AT HIGH TEMPERATURES
Abstract
The program resulted in the preparation an preliminary determination of some electrical and thermal properties of 17 intermetallic compounds, at least 6 of which have never previously been prepared. The main emphasis was the rapid survey of possible intermetallic compounds of a number of refractory metals with a photeric semi-metals, and their behavior as possible semiconductors. As a group, these compounds exhibited behavior ranging from metallic to semi-conducting and tended to decompose in a vacuum at only moderate temperatures. No promising high temperature thermoelectric materials were discovered, although an analysis under certain plausible assumptions indicates that a figure of merit of approximately 0.6 x 10 to the -3rd power could be obtained with more refined methods of preparation. Other compounds exhibited semi-conducting properties which may be of interest for applications other than t ermoelec ric generation. (Author)
