Abstract

We investigated single-walled carbon nanotube (SWNT) growth on electrochemically etched W tips by Co/Al catalyst-assisted chemical vapor deposition using ethanol as the carbon source. Vertically aligned SWNTs on the W tip apex were obtained by applying a voltage of 50 V to the W tip during the chemical vapor deposition. Also, we examined the field emission property of the vertically aligned single-walled carbon nanotube tip, and showed that it exhibits a low threshold voltage for electron emission. This growth method is useful for investigating the emission properties of individual SWNTs.
