High-Performing Flexible Mg₃Bi₂ Thin-Film Thermoelectrics.

ABSTRACT: With the advances in bulk Mg₃Bi₂, there is increasing interest in pursuing whether Mg₃Bi₂ can be fabricated into flexible thin films for wearable electronics to expand the practical applications. However, the development of fabrication processes for flexible Mg₃Bi₂ thin films and the effective enhancement of their thermoelectric performance remain underexplored. Here, magnetron sputtering and ex-situ annealing techniques is used to fabricate flexible Mg₃Bi₂ thermoelectric thin films with a power factor of up to 1.59 µW cm^-1 K^-2 at 60 °C, ranking as the top value among all reported n-type Mg₃Bi₂ thin films. Extensive characterizations show that ex-situ annealin
