Type: article

Abstract: Thermoelectric Devices In article number 2508990, Takao Mori and co-workers report a novel thermoelectric device design that accommodates an optimized cross-sectional area ratio without compromising the device's fill factor. The proof-of-concept is demonstrated using a fully Mg3Sb1.5Bi0.5-based thermoelectric device, showing a simultaneous improvement in both power and efficiency, suitable for medium-temperature power generation applications.
