Abstract
Present thermoelectric devices operate at about 10% of the Carnot efficiency, whereas the efficiency of compressor-based refrigerators is larger than 30%. An increase in the thermoelectric figure of merit ZT above 3 is needed before thermoelectric technology can replace current air conditioning technologies in many applications. Recent models have predicted that ZT can reach 6 in metal/HgCdTe superlattice-based devices. The ultimate goal of this project is to develop the technology required for the fabrication of HgCdTe-based thermoelectric devices with high thermoelectric figures of merit, monolithically integrate them with the silicon-based solar cells currently available at EPIR, and apply the technology to critical electronic equipment cooling and military base camp air conditioning purposes. The feasibility of using HgCdTe-based materials grown on silicon substrates for thermoelectric cooling will be demonstrated during Phase I. We will develop an accurate model for the thermoelectric properties of HgCdTe superlattice structures and perform the molecular beam epitaxy growth and characterization of these materials. In addition to materials development, EPIR will optimize and fabricate test device structures suitable for the extraction of the materials' thermal and electrical characteristics. We will measure device ZT and the coefficient of performance, and compare them with values obtained from modeling.
