摘要

A method for calculating the field-emission current from a single carbon nanotube in an external electric field directed along the nanotube is presented. The method is based on a semiclassical approach using the subbarrier-tunneling mechanism. It is shown that the current corresponds to the Nordheim-Fowler mechanism for field emission in the case of strong fields; in the case of weak fields, there are deviations associated with features of the behavior of the potential barrier.
