Controlling the diameter of carbon nanotubes

ORAL

Abstract

We report a method to control the diameter of an individual carbon nanotube. Electronic transport measurements performed in situ reveal a striking dependence of conductance on nanotube geometry. As the diameter of the nanotube is reduced to near zero, we observe negative differential resistance.
