Interaction of threading and misfit dislocations in a strained epitaxial layer
Abstract
The motion of a dislocation in a strained layer is calculated using continuum elastic theory. Blocking of the moving dislocation by a fixed misfit dislocation across its path is found to be weaker than previously believed. The calculation makes no approximation regarding the shape of the dislocation, and correctly includes the self-interaction of the moving dislocation. © 1996 American Institute of Physics.
