Abstract
A method for wafer transfer includes forming a spreading layer, including graphene, on a single crystalline SiC substrate. A semiconductor layer including one or more layers is formed on and is lattice matched to the crystalline SiC layer. The semiconductor layer is transferred to a handle substrate, and the spreading layer is split to remove the single crystalline SiC substrate.
