Cleaner Graphene Offers Better Device Performance
To transfer a thin sheet of graphene (yellow honeycomb) to a device being built, researchers first lower a sheet of graphene grown on copper (top left) into a petri dish containing an etchant. A graphite holder keeps the graphene in place. After etching away the copper, the researchers replace the etchant with solvent (light blue, bottom left) and slip the device (pink, “substrate”) under the floating graphene sheet (bottom right). Pumping away the solvent lowers the graphene onto the substrate (top right).
