Abstract

Stable field emitters were developed using carbon nanotubes (CNTs) composite pastes with nickel (Ni) buffer layer. The paste CNT emitters showed lower threshold for field emission but which have short lifetime and unstable emission current in high emission current. In this paper, we developed the simple process of inserting Ni buffer layer between the CNT emitters and substrate. The paste CNT emitters with Ni buffer layer showed enhanced field emission properties than bare one. The lifetime of paste CNT emitters with Ni buffer layer were 9 hours 40 min. It´s 22 times longer than without buffer layered one.
