Field electron emission characteristics of a wide variety of carbon nanomaterials have been investigated to clarify the relation between their structures and emission properties. The carbon nanomaterials were synthesized in methanol using cobalt (Co) as a catalyst on silicon (Si) substrates. The novel catalytic growth method was recently developed by our group. The method realized a simple, speedy, and high-purity growth of carbon nanomaterials in organic liquids. We have tried to grow carbon nanomaterials by the developed method under different growth conditions. The morphology of the grown materials was observed by scanning electron microscopy (SEM). The crystallinity of the carbon nanomaterials was measured by laser Raman spectroscopy. Field electron emission characteristics of the grown carbon nanomaterials were measured using diode-type electrodes in a high-vacuum chamber.
