“…For example, thermoelectric heat engines [15,17,[45][46][47] and thermoelectric refrigerators [16,[48][49][50][51][52]. Moreover, related applications have been developed in the field of thermal rectifiers/diodes [53][54][55][56][57], thermal transistors [58,59], and thermal logical gates [60]. Coulomb drag [61][62][63], thermometry [64][65][66] and quantum information [67][68][69][70].…”
