Abstract

Misfit dislocations are selectively placed in layers formed over substrates. Thicknesses of layers may be used to define distances between misfit dislocations and surfaces of layers formed over substrates, as well as placement of misfit dislocations and dislocation arrays with respect to devices subsequently formed on the layers.
