Resistance of copper nanowires and comparison with carbon nanotube bundles for interconnect applications using first principles calculations

摘要: We have studied the electronic properties and band structure of copper nanowires for various diameters using first principles density functional methods a supercell approach. The resistances were computed on basis Landauer formalism compared with those obtained from an empirical fundamental small (~60?nm diameter) are found to be larger than predicted by Ohm's law. In parallel, we bundles single walled carbon nanotubes them that wire similar dimensions. find resistance nanotube is smaller wires dimensions below 60?nm. Our results discussed in light recent experiments.
