Abstract

The misorientation of epilayer lattice planes in lattice-mismatched heterostructures is discussed. The geometry of the tilt reflects the overall symmetry of the system. Thus, rotation of tilt axis contains information on the anisotropy of dislocation nucleation/glide in low misfit, and on the initial growth processes in high misfit systems. In coherent systems, no rotation is expected. The model shows good agreement with experimental observations.
