ABSTRACT
Capacitance-voltage measurements have been performed on individual metal-carbon nanotube (CNT) Schottky diodes. The capacitance is found to agree in general with electrostatic simulations, taking into account the one-dimensional density of states of the CNT, and depends strongly on the Schottky barrier height and the diameter of the nanotube. The results indicate that the capacitance-voltage technique can be extended to characterize electrical junctions with very small area.

    Low-voltage nonstationary electron emission from single-walled carbon nanotubes after the passage of high autoemission current has been observed. This emission is assumed to be exoelectron emission associated with mechanical stresses and defects appearing in nanotubes due to electrostatic forces...
