Abstract

Pulsed laser treatment of an individual Multiwall Carbon Nanotube (MWCNT) exposed to a 248 nm excimer laser induced selective exfoliation of the amorphous carbon contamination layer. After the treatment, transmission electron microscopy (TEM) images show that the amorphous layer has expanded and separated from the crystalline MWCNT walls. This interesting observation has implications for laser cleaning and possible thinning of MWCNTs to reduce the radial dimensions.
