摘要

Intensive change in electronic structure of single wall carbon nanotube (SWCNT) bundles is observed, arising from intercalation of naphthalene into the interstitial spaces of the bundles with adsorption from solution. Ultraviolet photoelectron spectroscopy shows a clear increase in the density of states reaching the Fermi level, explicitly indicating pseudometallization of SWCNT by this simple and scalable intercalation method. On the other hand if a nonvolatile pentacene is deposited on the external bundle surface in vacuum, SWCNT shows no similar change in the density of states.
