摘      要：Active Peltier cooling enables Peltier heat transfer in addition to the traditional Fourier thermal conductance,which is useful in some special applications,such as the *** the material wise,however,the study on the active Peltier cooling materials is *** carried out a high-throughput workflow to screen out 5 room-temperature active Peltier cooling materials,GaSbLi_(2),HgPbCa_(2),SnTiRu_(2),GeYbLi_(2),and GeTiFe_(2),from 2958 Heusler *** the five materials are semimetals or very narrow band gap systems with high electrical *** of these materials have relatively large Seebeck coefficients due to the band *** effective thermal conductivityκ_(eff)s,which are the summation of active Peltier thermal conductivity and passive thermal conductivity,are all greater than Cu at the room temperature andΔT=1 *** present work gives a possible way to search active cooling Peltier materials for the applications of precise temperature control.
