Various bonding configurations of transition-metal atoms on carbon nanotubes: Their effect on contact resistance
نویسندگان
چکیده
Our investigations reveal that the bonding of the transition-metal atoms on a single-wall carbon nanotube ~SWCN! depends on the detailed contact conditions. On the basis of our results, we suggest that the early 3-d elements ~Sc, Ti, and V! can be expected to be good candidates for making metal–SWCN contacts of low resistance, while contacts employing the late 3-d elements ~Fe, Co, and Ni! and Cu are expected to exhibit large contact resistance. © 2000 American Institute of Physics. @S0003-6951~00!03326-X#

Metal–nanocarbon contacts
To realize nanocarbons in general and carbon nanotube (CNT) in particular as on-chip interconnect materials, the contact resistance stemming from the metal–CNT interface must be well understood and minimized. Understanding the complex mechanisms at the interface can lead to effective contact resistance reduction. In this study, we compile existing published results and understanding for two met...

In this paper, we predict the current-voltage (I-V) characteristics and contact resistance of “end-contacted” metal electrode-graphene and metal electrode-carbon nanotube (CNT) interfaces for five metals, Ti, Pd, Pt, Cu, and Au, based on the first-principles quantum mechanical (QM) density functional and matrix Green’s function methods. We find that the contact resistance (normalized to surface...
