[IEEE 2018 31st International Vacuum Nanoelectronics Conference (IVNC) - Kyoto, Japan (2018.7.9-2018.7.13)] 2018 31st International Vacuum Nanoelectronics Conference (IVNC) - Comparison of experimental and theoretical methods for determining the emission area of multitip field cathodes
摘要： The experimental and theoretical methods for obtaining the values of the emitting surface are considered. The obtained values of the emission area from the experimental current-voltage characteristic are compared with those derived using theoretical calculations and computer simulation.

The technique of visualization and evaluation of the emission site distribution for large area field emitters
摘要： This paper presents a method for online treatment of the distribution pattern of emission sites on the emitter surface, combined with a multichannel registration and processing system of the IVC. Using computerized field emission projector we have studied nanocomposite emitter based on carbon nanotubes "Taunit M" and polystyrene. The distribution pattern of emission sites over the brightness level was obtained as well as the emission area of the sample was determined. Time dependences of the current level, the total brightness and the emission area were registered.
