Abstract

The rapid growth of wearable electronics, health monitoring, and the Internet of Things has created a tremendous demand for flexible semiconductors and gadgets. Thermoelectric (TE) semiconductors that enable direct conversion between heat and electricity have been utilized as power generators, but their intrinsic brittleness inhibits the application for powering flexible/wearable electronics. The plastic inorganic semiconductors discovered in recent years offer a different option for flexible TE technologies when these materials combine good plasticity and high TE performance at room temperature. In this Perspective, we discuss how room-temperature plasticity affects the manufacturing process and real-world uses in flexible electronics, the trade-off between plasticity and thermoelectric performance, and the underlying deformation mechanisms. Further outlook on the discovery of viable plastic inorganic semiconductors is proposed.

具有室温可塑性的无机热电半导体

可穿戴电子设备、健康监测和物联网的快速发展对柔性半导体和小工具产生了巨大需求。热电半导体（TE）可实现热与电的直接转换，已被用作发电装置，但其固有的脆性阻碍了其在柔性/可穿戴电子产品中的应用。近年来发现的塑料无机半导体为柔性 TE 技术提供了另一种选择，这些材料兼具良好的可塑性和室温下的高 TE 性能。在本视角中，我们将讨论室温塑性如何影响柔性电子器件的制造工艺和实际应用、塑性和热电性能之间的权衡以及基本的变形机制。我们还对发现可行的塑性无机半导体提出了进一步的展望。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
