APPARATUS AND METHOD FOR INDUCING ELECTRICAL PROPERTY CHANGES IN CARBON NANOTUBES

摘要

An apparatus and process for fabricating carbon nanotubes ("CNTs") with specific diameters and morphologies, comprising a vacuum system, CNT holder and microwave source adapted for directing a microwave field onto the CNTs. The morphology selection can yield samples of pre-selected diameter configurations making it possible to take a sample of SWNTs produced by any synthesis technique and induce a morphology change that causes the sample to be either all conductive, all narrow band gap semi-conductive or wide band gap semi-conductive, within a given nanotube rope.
