High Performance Thermoelectric Cryocoolers Based on II-VI Low Dimensional Structures

Abstract

This program performed material design for high-performance thermoelectric (TE) cooler with a figure-of-merit ZT > 3. The cooler is fabricated from HgCdTe using a low dimensional superlattice structure. The TE coolers can operate at temperatures ranging from 30K to300K, thereby providing a fundamentally new and disruptive method for achieving cryogenic cooling. In this STIR program we investigated (1) Modeling of HgCdTe Low Dimensional Structures and (2) Thermoelectric Cooler Design and (3)Partnership with Amethysts Research Inc. and SCD.USA to investigate the feasibility of integrating the TEC into their new TECFPA/Dewar.
