Carbon nanotubes and their emission properties
National Research Centre ‘Kurchatov Institute’, pl. akad. Kurchatova 1, Moscow, 123182, Russian Federation
The current methods of synthesis and investigation of carbon nanotubes are reviewed. The interconnection between structural peculiarities and electronic characteristics of carbon nanotubes has been studied. The recently developed methods of growth of similar nanotubes with pre-assigned characteristics are described. The development of these methods offers the possibility of mass production and application of relevant devices. The phenomenon of electron field emission from carbon
nanotubes and possibilities of its usage in flat panel displays, gas discharge devices, etc. is analyzed. Prospects and real achievements in the area of application of nanotubes as cold electron emission sources are discussed.
