Carbon nanofibres from diamond film using Ar-ion bombardment and their field emission property

Carbon Nanofibers from Carbon Nanotubes by 1.2 keV Ar+ Sputtering at Room Temperature

“…Subsequent to the initial growth spurt, length and radius increased slowly with time. The investigations of carbon material (such as glass amorphous carbon, graphite, and diamond) irradiated by Ar + with energy of several keV show that the cone or protrusions could form by several ten min sputtering [12][13][14][15][16][17][18][19]. Hence, it is believed that the formation of cone or conical carbon protrusions is contributed to the competitive effects of the roughening process and the smoothing process.…”

“…Recently, the interaction between the carbon material and ion beam with energy of several keV has been studied, such as diamond [12], graphite and graphite paste [13,14], glassy carbon [15,16], and flexible plastic substrate [17][18][19]. These results show that the carbon nanofiber could form by ion sputtering and carbon nanofiber only grow on the tip of cone.…”

“…The interactions between high energy particles and CNTs have been extensively studied during the last several years [3][4][5][6][7][8][9][10][11][12][13]. Structural evolution of CNTs irradiated by in situ electron beam performed by Banhart et al showed that basal planes of CNTs appeared as rupture, tilting, and bending under the irradiation [3,4].…”
