Thermoelectric (TE) devices enable direct solid-state energy conversion from heat to electricity and vice versa, thereby showing great potential in warranting the supply of sustainable energy and mitigating the potentially catastrophic effects of climate change. Therefore, as a clean-energy-generation technology, TE materials have received tremendous research efforts in both industrial and academic communities for applications in the recovery of ubiquitous low-grade waste heat. Achieving high efficiency in TE materials is an ongoing pursuit of the TE research community, considering approximately 90% of all waste heat in the USA comes from medium-temperature (e.g., from 573 to 873 K) heat sources. Hence, synergistic enhancements in the figures-of-merit (ZT) are still highly desired and remain a key task for improving commercial applications of TE materials.

在多相材料中实现增强的热电性能

热电 (TE) 设备可实现从热到电的直接固态能量转换,反之亦然,从而在保证可持续能源供应和减轻气候变化的潜在灾难性影响方面显示出巨大潜力。因此,作为一种清洁能源发电技术,热电材料在工业界和学术界在广泛存在的低品位余热回收中的应用得到了巨大的研究努力。考虑到美国大约 90% 的废热来自中温(例如,从 573 到 873 K)热源,在 TE 材料中实现高效率是 TE 研究界的持续追求。因此,
