Plasmonic carbon interconnects to enable the THz technology: Properties and limits

This paper presents a realization of interconnects working in the THz range, based on the propagation of surface plasmons along carbon-based conductors, such as carbon nanotubes or graphene nanoribbons. Based on a quasi-classical transport model, the behavior of such interconnects is studied, highlighting not only the fascinating features of such realizations, but also the limiting factors due to new phenomena occurring in the THz range, such as plasmon and/or tunneling resonances. Experimental evidence of some of such phenomena is also shown.
