| Abstract: | Artificially tilted multilayer thermoelectric devices (ATMTDs) have attracted growing attention due to their ease in miniaturization and high flexibility in device design. However, most of these devices are inefficient due to the lack of effective strategy to optimize their material matching and geometrical configurations. Herein, a high-throughput optimization approach is employed to screen high-performance Bi2Te2.7Se0.3-based ATMTDs from a material genome database covering 230 kinds of candidates. 14 kinds of ATMTDs are found to have ZTzx,max values exceeding 0.3 and tilt angles greater than 15°. Bi0.1Sb1.9Te3/Bi2Te2.7Se0.3 ATMTD is screened out and fabricated because of its excellent transverse figure of merit, large tilt angle, and good interface compatibility. Consequently, transverse figure of merit over 0.3, thermal sensitivity greater than 0.11 mV·K?1, and power density up to 1.1 kW·m?2 are recorded in Bi0.1Sb1.9Te3/Bi2Te2.7Se0.3 ATMTD. This indicates that ATMTDs have great potential for application in the fields of temperature detection and power generation. |
