High-Temperature Broad-Band Semiconductors
Abstract
This report includes: RARE EARTH SULFIDES AS HIGH-TEMPERATURE THERMOELECTRIC MATERIALS, by S. W. Kurnick, M. F. Merriam, and R. L. Fitzpatrick. 20 Jan 61, (Rept. no. GA-1929) SOME REMARKS ON THE ULTIMATE PERFORMANCE OF RARE EARTH SULFIDES, by P. H. Miller, Jr. 1961. ON THE APPLICATION OF THE SEEBECK EFFECT IN SOLIDS, by J. Appel. 10 Mar 61, (Rept. no. GAMD-2091) Fundamental work on Ce-S was continued in the attempt to achieve better understanding of the electrical and thermal transport mechanisms of compounds having the Th3P4 structure. Work was begun on the synthesis and evaluation of related compounds which show promise as high-temperature thermoelectric materials. These are the Th3P4structure rare-earth sulfides of La, Pr and Gd. Theoretical interpretation included analysis of the Seebeck coefficient in polar semiconductors. Emphasis was placed on polaron theory, a transport mechanism which shows promise in application for the selection of better thermoelectric materials.
