异质结构和中空纳米结构都被预测为具有优异热电性能的候选物。在这篇研究新闻文章中，报道了一维异质结构（分段和核/壳）和管状纳米结构的合成策略，生长机制和热电性能的最新进展。对Te/Bi核壳异质结构纳米线和Bi 2 Te 3纳米管热电性能的研究表明，通过优化材料的Seebeck系数和热导率可以提高其热电性能。此外，目前的问题和未来的研究方向，有前途的热电纳米结构将讨论这些实验结果的基础上。
Both heterostructures and hollow nanostructures have been predicted as candidates with excellent thermoelectric performance. In this Research News areticle, recent advances with regard to synthetic strategies, growth mechanisms, and thermoelectric properties of one‐dimensional heterostructures (segmented and core/shell) and tubular nanostructures are reported. The thermoelectric property studies of Te/Bi core/shell heterostructured nanowires and Bi2Te3 nanotubes indicate that the Seebeck coefficient and thermal conductivity of these materials can be optimized to improve their thermoelectric performance. In addition, the current issues and future research directions for promising thermoelectric nanostructures will be discussed on the basis of these experimental results.
