Abstract: Methods for obtaining a free-standing thick (>5 ?m) epitaxial material layer or heterostructure stack and for transferring the thick epitaxial layer or stack to an arbitrary substrate. A thick epitaxial layer or heterostructure stack is formed on an engineered substrate, with a sacrificial layer disposed between the epitaxial layer and the engineered substrate. When the sacrificial layer is removed, the epitaxial layer becomes a thick freestanding layer that can be transferred to an arbitrary substrate, with the remaining engineered substrate being reusable for subsequent material layer growth. In an exemplary case, the material layer is a GaN layer and can be selectively bonded to an arbitrary substrate to selectively produce a Ga-polar or an N-polar GaN layer.
