Abstract

Various forms of carbon including nanodiamond, carbon nanotube (CNT)s, nanohorns, nanofibers, nanocluster or nanostructured carbon are being studied as materials for diverse applications. Many of these materials have been shown to be very low field electron emitters. The change in the sp3 and sp2 bonding ratio in these materials defines the material. Presented in this paper is a comparative study of low field electron emission from various nanocarbons. Most of these films exhibit low field electron emission of varying from 1 V/μm to 5 V/μm, for an emission current density of 1 μA /cm2. Discussed further in this paper is the possible correlation between the field emission properties and the Raman response.
