Abstract: In this paper we study the tunneling contact of carbon nanotubes with deep impurities and metal. The tunneling current in contact nanotube-metal was investigated. The dependence of current-voltage characteristic of such contact on the band gap of the impurity was analyzed. An area with negative differential conductivity was observed.

Keywords: сarbon nanotube, deep impurity, band gap, negative differential conductivity.
