摘　　要：本文报道了在碲锌镉(CZT)晶片(111)Cd面上发现的等边三角形和四边形形变,并在CZT(111)面上做了压力实验。结果表明我们所发现的多边形是碲锌镉在压应力作用下产生的,不仅可以在(111)Cd面出现,也可以在(1 11)Te面出现。文中从经典的晶体范性形变理论和面心立方闪锌矿结构晶体所具有的滑移特性出发,阐明了出现在CZT(111)Cd面的多边形的形成机理,其内角必为60°或120°。并对磨抛工艺提出了改进意见。This paper reports equilateral triangles and quadrangles deformation discovered on the （ 111 ） Cd faces of CdZnTe wafers. And the pressure experiment was done on the （ 111 ） faces of CZT wafers. The results show that those polygons appeared when the cadmium zinc teUuride was pressed. Here, according to the classical theory of plastic deformation of the single crystal and slip characteristic of the face centered cubic with zincblende structure crystal, the reasons why the polygons came into being were clarified. The polygons＂ internal angle must be 60° or 120°. And some improved suggestion was given to the polishing of CZT.
