In this study, we fabricated a cathode using screen printing method with carbon nanotubes and ZnO nanotetrapods as cathode emission materials and CsI nanoparticles as coating materials. After several comparative experiments, we find that 3g CsI dispersed into an organic paste which is composed of 20ml terpineol and 1g ethyl cellulose has significant results to improve the performance of the field...
In this paper, the authors report a simple method can control the CNTs distribution. The emission properties of screen-printed CNTs were improved after using with a wetting and dispersing additive simultaneously. Moreover, the screening effect of the agglomerated CNTs emitters are also numerically studied.
