Abstract

Clarifying the electron emission mechanism of diamond is one of the remaining problems for the realization of diamond cold cathodes for vacuum nano-electronics applications. Diamond is well known to have negative electron affinity (NEA) and an electric field of less than IV/um is required to extract electrons from the surface [1], whereas much higher field is needed for the conventional metal emitter tips. However, there have been only few reports attempting to clarify the mechanism based on the experimental results [2-4]. In this study, a combined spectroscopy of XPS/UPS/FES was performed to characterise the electron emission mechanism of diamond. As a result, we have succeeded in drawing the energy band diagram to explain the electron emission from various types of diamond.
