ABSTRACT
Carbon nanotubes (CNTs) are discovered materials made by rolled sheets of graphene of diameters of the order of nanometers and lengths up to millimeters. The theoretical predictions have been confirmed by the first real-world CNT-based electronic devices, like the CNT bumps for nanopackaging applications presented in or the CNT wiring of a prototype of a digital integrated circuit, one of the first examples of successful CNT-CMOS integration. This chapter presents the transport equation for carbon nanotubes, first considering isolated CNTs and then considering the case of interacting CNT shells, when the tunneling effect is considered. The transport equations are derived from an electrodynamical model that describes the behavior of the conduction electrons. The chapter describes the electrodynamics of the conduction electrons of carbon nanotubes (CNTs), and models are derived to study the propagation of signals along CNT interconnects.
