In this study, the field electron emission from the vertically well-aligned CNTs catalytically synthesized in liquid methanol was measured to determine the relation between the emission properties and their morphologies. Heavily doped n-type silicon (Si) wafers with a low resistivity less than 0.02 Ω cm were used as a substrate for the CNT growth. The morphology and fine structure of the grown CNTs...
Field emission characteristics of the carbon nanomaterials with different surface morphologies have been measured. They were catalytically grown in the organic liquid of 1-octanethiol (CH3(CH2)7SH) with using Co as a catalyst. A thick fibriform or a film-like structured carbon nanomaterial was grown by the control of the phisco-chemical states of Co catalyst. The thick fibriform materials indicated...
