Artificially-tilted multilayer transverse thermoelectric devices (ATMTTDs) have a large degree of design freedom, which is convenient for designing devices for different working conditions. However, evaluation and preparation of ATMTTDs has generally been based on trial and error, and coherent performance optimization strategies for different ATMTTDs applications is still lacking. Here, the relationship between performance evaluation indicators, transverse thermoelectric properties, and geometric structure parameters of ATMTTDs has been established via theoretical calculation and experimental verification. The results show that the tilt angle (θ) has a key effect on the transverse thermoelectric properties of ATMTTDs. The optimal transverse thermoelectric figure of merit, power factor, and Seebeck coefficient of Ni/Bi_0.5Sb_1.5Te₃ (BST) ATMTTDs are theoretically predicted at tilt angles of 11°, 21°, and 45°, respectively. Ni/BST ATMTTDs have been fabricated and the experimental results demonstrated that a maximum power generation efficiency of 1.01% and maximum effective refrigeration temperature difference of 0.4 K are reached at θ = 11°, maximum output power density of 411 W/m² is obtained at θ = 21°, and a maximum response sensitivity of 420 μV/K is achieved at θ = 45°, which is in good agreement with theoretical predictions. This work provides theoretical guidance for manufacturing ATMTTDs for different applications.

人工倾斜的多层横向热电器件（ATMTTD）具有较大的设计自由度，便于针对不同工况设计器件。然而，ATMTTDs的评估和准备通常基于反复试验，并且仍然缺乏针对不同ATMTTDs应用的一致的性能优化策略。在此，通过理论计算和实验验证，建立了ATMTTDs的性能评价指标、横向热电性能和几何结构参数之间的关系。结果表明，倾斜角（θ) 对 ATMTTD 的横向热电性能有关键影响。Ni/Bi _0.5 Sb _1.5 Te ₃ (BST) ATTTD的最佳横向热电品质因数、功率因数和塞贝克系数分别在倾斜角为 11°、21° 和 45° 时进行了理论预测。的Ni / BST ATMTTDs已经制造和实验结果表明，1.01％的最大发电效率和0.4的K最大有效制冷温度差在达到θ  = 11°，/ 411 W的最大输出功率密度米²获得在θ  = 21° 时，在θ处实现了 420 μV/K 的最大响应灵敏度 = 45°，这与理论预测非常吻合。这项工作为制造用于不同应用的 ATTTD 提供了理论指导。
