ABSTRACT
A terahertz (THZ) response of single-walled carbon nanotubes has been successfully observed and measured. Many unique applications of carbon nanotubes (CNTs) in the terahertz frequency range thus appear possible when the types of plasmon phenomena are well understood. This chapter presents large-scale quantum atomistic time-domain simulations to gain an in-depth picture of electron transport phenomena at very high frequencies in CNTs. It provides the preliminary results obtained using 3-dimensional time-dependent, numerical framework, making use of an atomistic, empirical pseudopotential, which has allowed use to capture the THz response of metallic CNT and accurately reproduce experimental results on the Fermi velocity and kinetic inductance. Effective modeling and propagation schemes are carried out to simulate the CNT THz response. CNTs have emerged as one of the most active areas of nanoscale science and technology research. Measurements on CNTs have been extended to about 60 GHz, and much higher frequencies are required to verify the properties of CNTs as predicted by existing theories.
