Misfit dislocations and stresses in CdxHg1-xTe/CdTe heterojunctions

Elastic properties and characteristics of misfit dislocations of CdxHg1-xTe /CdTe heterostructures were estimated: the energy density of the film-subst rate interface, the critical thickness for loss of coherency in a heterojun ction, the elastic strain in the epitaxial system, the length of the cracks in the epilayer, the free edge displacement of a layer, the misfit disloca tions spacing, the magnitude of Burgers vector lying in different misfit pl anes, and the interface dangling bond density.
