摘要

采用正电子湮没寿命谱方法对空间微重力及重力条件下生长的呼银汞（MCT）材料中的微观缺陷进行了研究。结果表明，在空间微重力条件下生长的MCT晶体中，其空位型缺陷浓度低于地球上有重句条件下生长的晶体，并且缺陷浓度沿轴向的分布比较均匀。

Abstract

The microstructures of vacancy-type defect in HgCdTe (MCT) samples grownunder micro-gravity condition were studied by positron lifetime measurements. Theresults showed that

the defect concentrations in the samples grown under spacendcro-gravity were lower than those grown under earth gravity on the ground. Thedistribution of defect concentration along the axial in the samples grown under spacemicro-gravity were more uniform than that grown under earth gravity on theground.
