Paper Abstract

Electron emission was obtained from discontinuous diamond thin films containing numerous carbon inclusions (diamond- carbon films) which were deposited on Mo using microwave chemical vapor deposition techniques. The films were characterized by X-ray diffraction, X-ray photoelectron spectroscopy and scanning electron microscopy. The square resistance of the films varied from 3 K(Omega) to 20 M(Omega) , and the maximum emission current of 1.4 mA was obtained from a broad emitting area of 15 X 5 mm2. The Fowler-Nordheim (FN) behavior of some samples was piecewise linear, which was similar to the typical FN curves of p-type silicon. A simple field emission device was demonstrated using the diamond-carbon cold cathode. The lower turn-on electrical field and higher current density was obtained from amorphous carbon-polyimide films deposited on silicon substrate by pulse laser deposition for the first time. The locations of electron emission sites were observed using transparent conducting anode technique.
