Graphitic interfacial layer is used to wet the surface of carbon nanotube and dramatically lower the contact resistance of metal to metallic single-wall carbon nanotube (m-CNT). Using Ni-catalyzed graphitization of amorphous carbon (a-C), the average resistance of metal/m-CNT is reduced by 7X compared to the same contact without the graphitic layer. Small-signal conductance measurements from 77K to 300K reveal the effective contact improvement.
