[1] Koeck F. A., Obraztsov A. N., Nemanich R. J. Electron emission microscopy of nano-crystal graphitic films as high current density electron sources // Diamond and Related Materials. — 2006. — Vol. 15, no. 4-8. — P. 875–879. Electron emission can be described by thermionic and field effects or a combination of both and can be characterized by the laws of Richardson-Dushman and Fowler-Nordheim, respectively. Nano-crystal graphitic films exhibit a film morphology comprised mainly of crystalline graphite sheets which are vertically aligned with respect to the substrate surface. Field emission from these films exhibits a low threshold field of < I V/mu m, an emission site density of similar to 3 x 10(5) /cm(2) and a significant distribution in brightness. The temperature dependence of the emission is complex and may be influenced by molecular adsorbates and interface reactions. For nano-cry stal line graphite films on molybdenum it was found that the emission current is significantly increased with temperature. The results suggest a field dependent barrier which may be an indication of field penetration. (c) 2006 Elsevier B.V. All rights reserved. [ DOI ]
