Imaging Wet Individual Single Walled Carbon Nanotube at Atomic Level
Abstract
Wet individual Single walled carbon nanotube was observed at an atomic level with high resolution. This observation was achieved in a liquid cell containing water using a modified non-contact mode atomic force microscopy (NC-AFM) which, we believed, becomes the powerful tool for imaging nano-material in atomic scale. Consequently, the topography image showed many hexagons network of carbon atoms forming the outer surface of SWCNT. The analysis of the scanned SWCNT, by NC-AFM probe, revealed the presence of two sites of an armchair and zigzag structures.
