A deeper understanding of quantum effects in nano-electronic devices helps to improve the performance and to develop new device types. Carbon nanotube-based transistors have been studied in recent years as potential alternatives to CMOS devices. The performance of carbon nanotube field-effect transistors is studied using the non-equilibrium Green's function formalism. Electron–phonon interaction parameters, such as electron–phonon coupling strength and phonon energy, strongly depend on the chirality and the diameter of the carbon nanotube. Therefore, the steady-state and dynamic response of carbon nanotube based transistors are studied for a wide range of electron–phonon interaction parameters.
