Topography and structure of nanocomposite C-Ni field emitters

In this paper we present results of structural and topographical studies of C-Ni nanocomposite films with different Ni content. Films were obtained by PVD method. Their structure was investigated by Raman and FTIR spectroscopy and topography by AFM. Typical field emission current from these films is few μA (up to 10 μA) for 3kV anode-cathode voltage and 0.1mm anode-cathode distance.
