Description
  • Carbon nanotubes (CNTs - long tubular carbon nanostructures) belong to the best electron field emitting materials. A code developed in FEMLAB enables numeric investigations of various aspects of field enhancement properties of CNTs. It was shown that there exist an optimum distance of neighboring nanotubes, for which the emitted electron current reaches its maximum, and that the current is strongly sensitive to the shape of the CNTs tips. To verify the reliability of the 3-D FEMLAB modeling we computed field emission characteristics of a conductive sphere placed in a homogeneous electric field and compared them with their theoretical values.
