Abstract

Single couple PbTe/TAGS-85 and thin-film superlattice Bi₂Te₃-based thermoelectric couples operated in a downhill active cooling mode, where the cold side temperature (T_c) is above that of the heat sink (T_h), are shown to be able to pump heat loads of 204 W/cm² (T_c ~ 300^°C) and 329 W/cm² (T_c ~ 150^°C), respectively, using a 25 ^°C heat sink temperature. Such TE devices would be useful in active cooling of wide bandgap RF electronics operating ~ 300^°C and ~ 150^°C, respectively.
