Zn掺杂对GeTe合金热电性能的影响
Effects of Zn Doping on the Thermoelectrical Properties of GeTe Alloy
摘要
Abstract
With high energy ball milling and direct current rapid hot pressing technology,the sampels of ZnxGe1-xTe alloys (x =0,0.01,0.02,0.03,0.04) were fabricated.The microstructures of the samples were characterized and the effects of Zn doping on thermoelectric properties of GeTe alloy were studied.The results indicate that all the samples are consolidated in single GeTe phase.In a certain extent,doping with Zn can improve the thermoelectric performance of GeTe material.The samples of Zn0.02 Ge0.gs Te and Zn0.03Ge0.97Te show better thermoelectrical performance among all the samples,whose peak ZT values reached 1.4 and 1.33 at 773 K respectively.关键词
