材料纳米化提高热电性能

摘要

Starting from the approaches to raising the thermoelectric efficiency, this paper explains the three concrete plans （elements-ingots-nanocompounds, elements-nanocompounds and nanoproducts） to enhance thermoelectric performance by the material nanocrystallization tactics and verifies the feasibility of those plans through introducing some concrete examples.%从提高热电效率的途径入手，着重阐述采用材料纳米化这一策略以大幅提升热电性能的3种具体方案（单质-合金锭-纳米化合物、单质-纳米化合物、纳米目标产物），并通过介绍一些具体实例验证这些方案的可行性。
