了填充化合物LayCo3.5Fe0.5Sb12与未填充化合物Co3.5Fe0.5Sb12的热电性能.结果表明,稀土元素La的填充使热导率显著下降,但同时也降低了功率因子,导致材料热电优值上升不大.因此,要提高材料热电优值,还须优化材料电性能. 关键词:半导体; 热电材料; 电性能; 热性能; semiconductors; thermoelectric materials; electrical properties; thermal properties; [全文内容正在添加中] ......
Fe-Co-Si-Cu热电材料的输运特性 李伟文1,曹高劭1,朱铁军1,赵新兵1 (1.浙江大学硅材料国家重点实验室,浙江,杭州,310027) 摘要:采用真空悬浮熔炼和真空退火方法制备了Fe1-xCoxSi2-0.1at%Cu热电材料.试样的微观组织中包含大量尺寸在1μm左右的小孔和一些裂纹.输运特性测量结果表明,550K时掺杂载流子的热激发达到饱和,700K以上发生本征激发现象.实验发现Co的最佳掺杂量为1at%左右,名义组成为Fe0.97Go0.03Si2-0.1at%Cu的试样的热电性能最好. 关键词:热电材料; 输运特性; 功率因子; 微观组织; thermoelectric materials; transport properties; power factor; microstructure; [全文内容正在添加中] ......
