▎ 摘　　要

This paper presents a simple, low-cost, and versatile approach based on the technique of electrophoretic deposition for developing high-performance carbon nanotubes (CNT)/graphene hybrid field emitters and examines their field emission properties. The fabricated CNT/graphene hybrid structure is found to display superior field-emission properties compared to those of pure CNT and pure graphene films. Low turn-on field and threshold field values of 1.0 and 2.3 V/mu m, respectively, were demonstrated for the fabricated hybrid structure. The paper also presents for the first time a study of field emission stability in CNT/graphene hybrid material fabricated by electrophoretic deposition. (C) 2015 American Vacuum Society.
