ABSTRACT: The field emission current from a
carbon fiber is considered. As a model of emission of an elementary carbon
tube, tunnel ionization of an electron from a short-range potential is taken.
The exact solution for the wave function in such a model allows obtaining an
asymptotic expression for electron current. A computer model of transverse
distribution of emission current of a carbon fiber is built on the basis of the
Monte Carlo method that allows taking into account the random character of
distribution of local emitter sources and the distribution of gains of an
electric field in carbon nanotubes.
