摘要/Abstract

摘要：

利用不同掺杂剂PbI₂,Al和Zr对制备热电材料n-PbTe载流子浓度的影响, 采用单向固化法制备具有连续载流子浓度的功能梯度热电材料. 测试结果表明, 连续载流子浓度的功能梯度材料PbTe比相同浓度焊接的功能梯度材料输出效率提高约30％. 

关键词: 功能梯度材料(FGM), 载流子浓度, PbTe, 有效最大输出功率

Abstract:

n-PbTe with continuous carrier concentration gradient as a functional graded material (FGM) was successfully solidified along the unidirectional temperature grade. The carrier concentration gradient was optimized by different dopants of PbI₂,Al and Zr and solidifying temperature grade. The effective maximum output power for continuous FGM PbTe is near 30％ larger than that for jointed FGM PbTe with the same carrier concentration.

Key words: functional graded material (FGM), carrier concentration; , PbTe, effective output power
