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...
In this paper, in order to compare the relationship between carbon nanomaterials structure and emission properties, carbon nanomaterials were synthesized and catalytically grown in methanol using cobalt (Co) catalyst on silicon substrates. The grown material morphology was observed using SEM and was changed by growth temperature. The crystallinity of the carbon nanomaterials was measured by laser...
In this paper, field emission characteristics in relation to structural properties of Marimo carbon were investigated. The morphology of the grown carbon was investigated using SEM and TEM was used for investigation of fibriform nanomaterials fine structure. Emission current was measured as a function of anode voltage. Results showed that spherical shape like as "Marimo" was observed with...
