摘要

梯度合成是提高热电材料性能系数Z的策略之一。梯度成分TE材料有两种。一种是载流子浓度功能梯度材料(FGM)，在一定的温度梯度下，对载流子浓度进行优化，使其产生最大的局部Z。另一种是分段FGM，由不同的材料组成，每个片段在其最佳温度范围内工作。综述了这两种类型的TE女性生殖器切割的研究进展。

Gradient composite thermoelectric materials

Gradient composition is one of the strategies for increasing the figure of merit Z of thermoelectric (TE) materials. There are two types of gradient composition TE materials. One is a carrier concentration functionally graded material (FGM), in which the carrier concentration was optimized to produce the maximum local Z with a certain temperature gradient. The other is a segmented FGM, which was composed of different material and each segment works at its optimal temperature range. The study progress of those two types of TE FGM is reviewed.
