Description
  • Carbon nanotubes belong to the best electron field emitting materials. Based on the experimentally determined electron density in the dual hot filament/DC plasma deposition system the electric field close to the substrate and ion energy flux were calculated. The dependences of electric characteristics close to the nanotube tips on various geometric and plasma parameters were numerically investigated. Taking into account the field enhancement in the vicinity of the CNTs tips the force acting on them was determined. The reliability of numeric computations was tested on a model of conductive sphere placed in a homogeneous electric field, for which theoretical predictions can be derived.

  • Uhlíkové nanotrubice patří k nejlepším emisním materiálům. Na základě experimentálně stanovené elektronové hustoty v duálním deposičním plazmatickém systému se žhaveným vláknem je počítáno elektrické pole poblíž substrátu a iontový proud dopadající na substrát. Numericky byla studována závislost elektrických charakteristik poblíž zakončení nanotrubic na různých geometrických a plazmových parametrech. S uvážením faktoru zesílení pole byla vypočtena síla působící na zakončení nanotrubic. Spolehlivost numerického algoritmu byla testována na modelu vodivé koule umístěné do homogenního elektrického pole, pro níž lze odvodit teoretické předpovědi. (cs)
