An ab initio description of cleaning of SWNT with UV light

ORAL

Abstract

The photodesorption of molecules and its application to the cleaning of single walled carbon nanotubes (SWNTs) has been experimentally demonstrated using a 248 nm laser. The excitation of the carbon nanotube $\pi$-plasmon is thought to couple to vibrational modes of the molecule-nanotube bond. An \it{ab initio}\normalfont \ inquiry seeks to validate this hypothesis and optimize the process of nanotube cleaning. The response of SWNTs to an electric field, a description of the enhancement of surface plasmons, and the role of hot electrons are discussed.
