HUNTER

Peltier, thermoelectric cooling modules (TEC) are made of arrays of n- and p-type semi-conductors. The efficiency is given by the Figure of Merit - ZT. The majority of thermoelectric solutions are based on rare-earth materials such as tellurium which constitute 90% of the global market. Bismuth telluride (Bi2Te3) and its solid solution alloy Bi2-xSbxTe3 (p-type), Bi2Te3-xSex (n-type) are the commercial state of the art material with peak ZT 1.0 @ 80oC and average ZT over TEC operating temperature of 0.8. HunTER will further develop and enhance the thermoelectric properties of Bi2Te3 systems based on phonon scattering, grain boundary engineering, metal-semiconductor interface for electron filtering and single stage hot-pressing (sintering and diffusion bonding). Thermoelectric coolers currently manufactured have a typical hot-side temperature of 50-55oC and a low side temperature of 0-5oC. The peak ZT for current Bi2Te3 systems falls outside of the normal operating temperatures. Within..
