MIT has proved that semiconductor epitaxy can be performed on a graphene-coated wafer, allowing the circuit or devices to be peeled off, and the wafer fully re-used. A nickel film peeled from a silicon wafer demonstrates the concept The epitaxy grows with its crystal structure aligned with the crystalline structure of the wafer below the ...
