The Question of Thermoelectric Devices Electrical Resistance—A Practical Investigation From a Peltier Effect (Thermoelectric Cooler/Thermoelectric Heater) Perspective

Heat Transfer, EarlyView.
ABSTRACT Thermoelectric devices (TEDs) intrinsic electrical resistance is fundamental to its operation. This internal electrical resistance value negatively affects a TED's performance when it is operated as a thermoelectric cooler (TEC), and positively affects a TED when operated as a thermoelectric heater (TEH).

Designer Entropy Enables High Thermoelectric Power and Efficiency

Interdisciplinary Materials, EarlyView.
Designer Entropy enables targeted control of defect and transport behavior in SnTe‐based alloys, allowing efficiency and power to be independently optimized. Radius‐matched Sb doping preserves carrier mobility and delivers superior power output, while Bi‐induced disorder suppresses mobility despite comparable efficiency.
