Abstract

在全球能源危机与环保技术日益受到重视的背景下, 热电材料因能实现热能与电能的直接转换而成为研究热点. 近年来, 通过纳米结构工程、能带工程及高熵工程等策略, 热电材料的性能显著提升. 其中, 高熵材料设计是热电领域的前沿方向之一. 其核心理念是利用多种主要元素占据同一晶格位点, 构筑具有高度无序特征的晶体结构. 基于这一独特结构, 高熵材料表现出四种核心效应, 为协同优化热电性能开辟了新途径. 本文围绕四大核心效应中的晶格畸变效应, 系统阐述其微观机制, 深入分析其对电输运和热输运性能的影响, 并进一步揭示高熵材料中晶格畸变与电声输运之间的复杂关系, 旨在为高熵热电材料的优化设计提供理论指导.
