Abstract

Monolithic lattice-mismatched semiconductor heterostructures are fabricated by bonding patterned substrates with alternative active-area materials formed thereon to a rigid dielectric platform and then removing the highly-defective interface areas along with the underlying substrates to produce alternative active-area regions disposed over the insulator and substantially exhausted of misfit and threading dislocations.
