用高分辨电子显微镜观察了碲镉汞晶体中的缺陷。直接观察到晶体中存在的两类60°位错。在孪晶边界上,观察到孪晶位错。指出,孪晶位错是再结晶过程中,孪晶界面迁移的激活台阶。The defects in Hg1-xCdxTe crystals are observed using HREM. Two kinds of 60° dislocation as well as the twin dislocation in the twin-plane boundary are obserred directly. It is showed that twin dislocation is the activated step of the migration of twin-plane boundary during recrystallization.
