A theoretical model describing the nucleation of misfit dislocations in interfaces between films and plastically deformed substrates with disclinations was proposed. The ranges of the parameters (disclination strength, density of the disclination ensemble, film thickness, and degree of misfit) within which misfit dislocation nucleation was energetically favorable were found. It was shown that at certain strengths of disclinations and densities of their ensemble the critical thickness of the film on a plastically deformed substrate with disclinations could exceed that on an undeformed defect-free substrate by a few times.
