扩散阻挡层材料对热电组件的结构可靠性和性能稳定性起着重要的作用。通过比较势垒材料/TE衬底界面的互扩散，从各种候选势垒材料中筛选出较好的势垒材料。传统上，对于每一种候选势垒材料，都必须对TE元件(电极/势垒材料/TE材料)进行复杂的加工处理才能获得相应的界面，这使得筛选工作既昂贵又耗时。在本文中，我们利用高通量策略，开发了一种高效的屏障材料筛选方法。通过简单地按照TE材料的烧结参数，将TE衬底材料和各种候选阻挡层材料的混合物共烧，将各种微观界面集成到一个样品中。这使不同界面的并行时效和微观结构表征成为可能，并且可以快速筛选出首选的阻挡材料。因此，它使TE模块的设计和优化更加高效和经济。
Diffusion barrier materials play an important role in both structure reliability and performance stability of thermoelectric (TE) modules. Preferred barrier materials are screened out from various candidates by comparing the interdiffusion at the barrier material/TE substrate interfaces. Traditionally, for each barrier material candidate, complicated fabrication processing of TE elements (electrode/barrier material/TE material) must be finished to obtain relative interfaces, which makes the screening costly and time consuming. In this article, using a high-throughput strategy, we developed a high-efficiency screening method of barrier materials. By cosintering the mixture of TE substrate material and various barrier material candidates simply following the TE material's sintering parameters, various microinterfaces were integrated to one single sample. This enables parallel aging and microstructure characterization of different interfaces, and preferred barrier materials can be swiftly screened out. As a result, it makes the design and optimization of TE modules much more efficient and economical.
