Graphene ‘copy machine’ may produce cheap semiconductor wafers

Graphene ‘copy machine’ may produce cheap semiconductor wafersA 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.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.
