Abstract

The radial charge distribution on the positive inner electrode of a cylindrical molecular capacitor was studied using a double-walled carbon nanotube. The radial charge distribution was revealed by resonant Raman scattering from phonons on each carbon shells. It was found by a self-consistent tight binding model that most of the charge resided on the outer wall, even when this wall was originally semiconducting and the inner wall was metallic.
