The process of the lattice damage and its development in the Hg1-xCdxTe crystal under electron irradiation with high dose and high energy have been studied at lattice level by high resolution electron microscopies. The results indicate that Hg1-x CdxTe lattice damage was caused by the deformation of the [(Hg, Cd)Te4] tetrahedra due to the strong electron irradiation. These deformations could be seen on the {111} plane and they developed along the {111} plane as steps. Moreover, a new superlattice with larger parameter of unit-cell was observed along the [110] direction.
