An energy criterion for the nucleation of a circular prismatic misfit dislocation loop in a spheroidal inclusion modeling a quantum dot was considered. The critical radius of the inclusion, for which the misfit dislocation loop could nucleate, was studied as a function of the lattice misfit between the inclusion and the matrix.
