Claim Text:
1. A method for creating semiconductor structure, having a single crystal multi-element semiconductor with a first lattice constant, on a crystalline semiconductor substrate having a second lattice constant different from the multi-element semiconductor, the method comprising: forming an insulator layer over a first top surface of the semiconductor substrate; forming an intermediate layer over a second top surface of the insulator layer; forming an opening in the intermediate layer to create an exposed region of the second top surface of the insulator layer; forming an opening in the exposed region to create an exposed area of the first top surface of the semiconductor substrate; depositing a first element of the multi-element semiconductor onto the exposed region, into the opening in the exposed region, and onto the exposed area; forming a capping layer that extends over the first element of the multi-element semiconductor; melting the first element of the multi-element semiconductor forming a melt, the melt encapsulated between the capping layer, the exposed region, and the exposed area; diffusing a quantity of a second element of the multi-element semiconductor through the capping layer and into an enclosed region formed by the capping layer, the intermediate layer, the exposed region, and the exposed area; creating a liquid solution by dissolving the quantity of the second element diffused into the enclosed region into the melt; and growing a single crystal multi-element semiconductor, seeded off the semiconductor substrate, from the liquid solution.
