A theoretical model of misfit dislocations and their dipole configurations in nano-scale films with compositional inhomogeneities was suggested. Energy characteristics of misfit dislocation dipoles were calculated. The critical film thickness was estimated which characterizes the energetically favourable generation of misfit dislocation dipoles in films with compositional inhomogeneities.
