| 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. |

| Keywords: | PbTe functional graded material (FGM) carrier concentration PbTe effective output power |
