Claim:
1. A structure, comprising: a substrate having a top surface; a first semiconductor layer disposed on the top surface of the substrate, the first semiconductor layer having a first unit cell geometry and comprising implanted ions; a layer comprised of a metal-containing oxide disposed on the first semiconductor layer; a second semiconductor layer disposed on the layer comprised of the metal-containing oxide, the second semiconductor layer having the first unit cell geometry; a third semiconductor layer disposed on a top surface of the second semiconductor layer; where the layer of metal-containing oxide has a second unit cell geometry that differs from the first unit cell geometry to inhibit propagation of misfit dislocations from the first semiconductor layer into the second semiconductor layer and from the second semiconductor layer into the third semiconductor layer, where the misfit dislocations originate from nucleation centers formed by the implanted ions in the first semiconductor layer; where the second semiconductor layer is comprised of Si
