Abstract: Carbon fibers, in thin film form, have been synthesized on Si substrates via direct current plasma enhanced chemical vapour deposition with acetylene as a precursor using Ni as a catalyst at substrate temperature 750-850°C. X-ray diffraction studies confirmed the graphitic phase of the carbon fibers. Surface morphologies of the films have been studied by a scanning electron microscope and an atomic force microscope. The graphitic carbon fibers have showed good field emission properties with a turn-on field lying in the range 2.57-9.71 V/ m for films deposited with different substrate temperatures. The field enhancement factor and the approximate work function have also been calculated. The emission properties have been studied for different anode-sample spacing for the carbon fibers film deposited at 850°C.
