Abstract

We demonstrate that a tweezers tip can be directly used to manipulate single-walledcarbon nanotube (SWCNT) films and individual SWCNTs (or bundles). Specifically, wecan align, bend, and even cut SWCNTs on the substrates where they are grown.With this manipulation technique, we are able to control the position, direction,and length of SWCNTs and fabricate complex patterns. Because of the largesize of the tweezers tip, long SWCNTs (hundreds of micrometers in length) arefound to be critical for the realization of such manipulations. This finding wouldcontribute to the property studies on nanotubes and the fabrication of nanodevices.
