Abstract

Misfit dislocations in thin film heterostructures were investigated. The misfit dislocation network consisted of approximately 60% of 90° dislocations, 40% of 60° dislocations. The 60° dislocation pairs had parallel screw components and as a result they cannot combine to form a 90° dislocation. The changes in the nucleation barrier for the 60° dislocations caused by the interaction with the existing misfit dislocations were also calculated.
