Abstract :
Based on large-scale ab-initio calculations contact properties of carbon nanotubes field effect transistors with 9-nm channel were analyzed. We have found that the internal part of the nanotube is metalized, while the uncovered CNT portion is p-doped due to the influence of the metal. Our findings can explain unique scaling of the CNT-FETs based on first-principles.
