Graphene 'copy machine' may produce cheap semiconductor wafers

A new technique may vastly reduce the overall cost of wafer technology and enable devices made from more exotic, higher-performing semiconductor materials than conventional silicon. The new method uses graphene — single-atom-thin sheets of graphite — as a sort of ‘copy machine’ to transfer intricate crystalline patterns from an underlying semiconductor wafer to a top layer of identical material.
