Carbon nanotubes (CNTs) have been studied in recent years due to their exceptional electronic, opto-electronic, and mechanical properties. To explore the physics of carbon nanotube field-effect transistors (CNT-FETs) self-consistent quantum mechanical simulations have been performed. The performance of carbon nanotube-based transistors is analyzed numerically, employing the non-equilibrium Green's function formalism. Electron-phonon interaction parameters, such as electron-phonon coupling
