1 Introduction
Methods for nanostructuring – the fabrication of structures with sizes on the nanoscale – are required for the fabrication of next-generation nanoelectronics, such as quantum-based devices, for nanophotonics, nanobiotechnology
physical process of emission is quantum mechanical tunneling of the electrons through the potential barrier, which is tilted due to the electric field (see Figure 14b for a schematic description of the tunneling process).
The theory of electronfieldemission from metals was developed by Ralph H. Fowler

The fundamental importance of light in our lives cannot be overstated. The sun is the only natural source of light emission with appropriate intensity
-like materials, having the strongest interatomic interaction, are attractive for the FE cathode production. In this paper we describe the production technique and the electronfieldemission (FE) characteristics of nano-graphite films (NGF) and prototypes of CL lamps with NGF cold cathodes.
Results and
of a strong electric field during the cold emission. The quantum tunneling character of the electronfieldemission process is responsible for the extremely low energy consumption of the electron beam production. Together with an appropriate lamp design, the cold electron emission from NGF provides
