摘要
Quantum dots and wires, having a mismatch of crystal lattice parameters with respect to the surrounding matrix, are modelled by spherical and cylindrical inclusions, respectively. By considering the energy of a circular prismatic dislocation loop nucleation in the inclusions, the critical radius and critical dilatation for a dot and a wire are calculated. The results are compared with similar critical parameters for a mismatched film on a substrate.
