    Abstract: A method for forming an epitaxial layer (4) involves depositing a buffer layer (2) on a substrate (1) by a first deposition process, followed by deposition of an epitaxial layer (4) by a second deposition process. By using such a dual process, the first and second deposition processes can be optimized, with respect to performance, growth rate, and cost, for different materials of each layer. A semiconductor heterostructure prepared by a dual deposition process includes a buffer layer (2) formed on a substrate by MOCVD, and an epitaxial layer (4) formed on the buffer layer (2), the eptitaxial layer deposited by hydride vapor-phase deposition.
