Double-wall carbon nanotube interconnects: experimental measurements, physical and circuit modelling

Abstract

Double-wall carbon nanotubes (DWCNTs) contacted by optimised Ti electrodes have been investigated. By using the described contacting technology, the DWCNT can be used as an ideal interconnect. Examining the dynamic response of the DWCNT interconnect, it is shown that the DWCNTs are faster than single wall carbon nanotubes (SWCNTs). Two conducting shells provide DWCNTs a lower resistance than SWCNTs. Experimental measurements and physical models have been used to develop a circuit model for simulating the DWCNT's current and dynamic response as an interconnect.
