Abstract

The electron field emission performance of screen-printed graphene cathode was studied. High-yield graphene was prepared by a modified Hummers method and hydrazine hydrate reduction process, and screen printing technology was used to prepare the graphene field emission cathode. This cathode structure satisfies the requirements of both good electrical conductivity and a high surface field enhancement factor, leading to excellent and stable field emission properties with a low threshold field (∼1.5Vνm^-1). Our work introduced a simple and convenient method suitable for large scale on different substrates, paving the way for more applications of graphene films.
