Statistical dependence of nanocomposite emission parameters

Abstract

Development of a unique computerized technique based on our program written by LabVIEW 2013 permitted us to register fluctuations of microscopic emission parameters of flat multiple-point cathodes and associate them with a statistical distribution of nanotube effective heights. Numerical estimates by Pearson show that this statistic is subject to lognormal distribution. In present work the influence of the emission current level on the statistical parameters of nanocomposite polystyrene -carbon nanotubes field emitter emission characteristics was studied.
