Highly\nConductive Doped Hybrid Carbon Nanotube–Graphene\nWires

Abstract

The following paper\nexplores the nature of electronic transport\nin a hybrid carbon nanotube–graphene conductive network. These\nnetworks may have a tremendous impact on the future formation of new\nelectrical conductors, batteries, and supercapacitors, as well as\nmany other electronic and electrical applications. The experiments\ndescribed show that the deposition of graphene nanoflakes within a\ncarbon nanotube network improves both its electrical conductivity\nand its current-carrying capacity. They also show that the effectiveness\nof doping is enhanced. To explain the effects observed in the hybrid\ncarbon nanotube–graphene conductive network, a theoretical\nmodel was developed. The theory explains that graphenes are not merely\neffective conductive fillers of the carbon nanotube networks but also\neffective bridges that are able to introduce additional states at\nthe Fermi level of carbon nanotubes.
