Abstract

A theoretical model and computations of the I-V characteristics of long carbon nanotubes in a strong axial dc field at room temperature is presented. Negative differential conductivity is predicted. It is shown that |dI/dV| for metal carbon nanotubes in the region of the negative differential conductivity significantly exceeds corresponding values for semiconducting ones. The predicted effect would enable the design of wave-generating nanotube-based diodes for submillimeter and infrared ranges.
