We propose a novel bottom-up procedure to easily fabricate a graphene-based device. The graphene was obtained in form of nanoplatelets, by microwave irradiation of commercial intercalated graphite, i.e., an environmentally friend, fast and low-cost procedure. The process used to create the contact between graphene nanoplates and copper was driven by the application of a DC electrical field in the gap between the electrodes, yielding the self-assembly of a graphene carpet in the gap. The electrical resistance of the device has been measured as a function of gap length and device temperature. The stability and reproducibility of the measured results demonstrate the reliability of the whole fabrication procedure, thus making it potentially attractive for industrial applications

Abstract

We propose a novel bottom-up procedure to easily fabricate a graphene-based device. The graphene was obtained in form of nanoplatelets, by microwave irradiation of commercial intercalated graphite, i.e., an environmentally friend, fast and low-cost procedure. The process used to create the contact between graphene nanoplates and copper was driven by the application of a DC electrical field in the gap between the electrodes, yielding the self-assembly of a graphene carpet in the gap. The electrical resistance of the device has been measured as a function of gap length and device temperature. The stability and reproducibility of the measured results demonstrate the reliability of the whole fabrication procedure, thus making it potentially attractive for industrial applications
