“…There are many studies on the FE of CNT arrays and/or films of different configurations and fabricated using different methods [83,112,113], and most of them have reported emission currents ranging from 1 mA • cm −2 to 1 A • cm −2 . One limitation on CNT emitters achieving higher FE current density is considered to be the too weak junction between CNTs and their substrate against Coulomb force [114]. Kato et al developed a CNT rooting technology using titanium carbide, which allows the strong junctions during operation of CNT field emitters to be retained [114].…”

There is a growing trend to apply field emission (FE) electron sources in vacuum electronic devices due to their fast response, high efficiency and low energy consumption compared to thermionic emission ones. Carbon nanotubes (CNTs) have been regarded as a promising class of electron field emitters since the 1990s and have promoted the development of FE technology greatly because of their high electrical and thermal conductivity, chemical stability, high aspect ratio and small size. Recent studies have shown that FE from CNTs has the potential to replace conventional thermionic emission in many areas and that it exhibits advanced features in practical applications. Consequently, FE from nanotubes and applications thereof have attracted much attention. This paper provides a comprehensive review of both recent advances in CNT field emitters and issues related to applications of CNT based FE. FE theories and principles are introduced, and the early development of field emitters is related. CNT emitter types and their FE performance are discussed. The current situation for applications based on nanotube FE is reviewed. Although challenges remain, the tremendous progress made in CNT FE over the past ten years indicates the field's development potential.
