Shape transition and dislocation nucleation in strained epitaxial islands
Jalkanen,J.; Trushin,O.; Granato,E.; Ying,S.C.; Ala-Nissila,T.We study numerically the equilibrium shape, shape transition and dislocation nucleation in strained epitaxial islands with a two-dimensional atomistic model, using interatomic potentials of Lennard-Jones type. The phase diagram for the equilibrium island shapes as a function of island size and lattice misfit with the substrate is obtained by an energy minimization procedure which does not require predefined fac...
Surface instability and dislocation nucleation in strained epitaxial layers
Trushin,O.; Granato,E.; Ying,S.C.; Kosterlitz,J.M.; Ala-Nissila,T.; Salo,P.We have studied numerically the stability and defect nucleation in epitaxial layers on a substrate with lattice mismatch. Stress relaxation and energy barriers for misfit dislocation nucleation are estimated using modern methods for saddle point search based on a combination of activation with local repulsive potential and the Nudged Elastic Band method. Stress relaxation processes correspond to different trans...
