TLDR
In this paper, the resistance of single and multi-wall carbon nanotubes (MWCNs) has been investigated and compared with the model presented in this paper for single and few-wall MCN.Abstract:
Equivalent circuit models are presented for the resistance of single- and multi-wall carbon nanotubes (MWCNs) that capture various electron-phonon scattering mechanisms as well as changes in the number of conduction channels as a function of temperature. For single- and few-wall nanotubes, the temperature coefficient of resistance (TCR) is always positive and increases with length. It reaches 1/(T-200 K) for lengths much larger than the electron mean free path, where T is the temperature in kelvin. For MWCNs with large diameters (>20 nm), TCR varies from -1/T to +0.66/(T-200 K) as the length varies from zero to very large valuesread more

Analyzing Conductance of Mixed Carbon-Nanotube Bundles for Interconnect Applications
S. Haruehanroengra,Wei Wang +1 more
TL;DR: In this article, a diameter-dependent model was introduced to analyze the conductance of both single-wall and multi-wall CNTs and MWCNTs, and the results showed that the mixed CNT bundles can provide two to five times conductance improvement over copper by selecting the suitable parameters such as bundle width, tube density, and metallic tube ratio.

Multichannel ballistic transport in multiwall carbon nanotubes.
TL;DR: The experimental observations imply a multichannel quasiballistic conducting behavior occurring in the MWCNTs with large diameter, which can be attributed to the participation of multiple walls in electrical transport and the large diameter of the M WCNTs.
