Dispersion Impact on Ballistic CNTFET n+-i-n+ Performances

The designs integrating the promising carbon nanotube transistors (CNTFET) will have to take into account the constraints implied by the strong dispersion inherent to nanotube manufacturing. This paper proposes to characterize the main CNTFET performances : on-current Ion, Ion/Ioff ratio and inverse sub-threshold slope S according to the dispersion on the nanotube diameter. For this purpose, we use a compact model suitable for testing several diameter values.
