In Situ FT-IR Study of an Electron-Beam Induced Reaction of C₆₀ Film

Abstract

The structural modification induced by electron-beam (EB) in a C₆₀ film and its kinetics have been studied using in situ high-resolution FT-IR spectroscopy. Similar to studies on photoirradiated K_xC₆₀ fim, was found that a coalescence reaction between adjacent C₆₀ molecules takes place. In order to investigate the interaction between an incident electron and Cgg molecules, the time-dependence of the amounts of C₆₀ on the EB irradiation was examined. It was found that the reaction rate exhibits a linear dependence on the reactant concentration and nonlinear dependence on the incident current.
