Observation of Quantum Capacitance of individual single walled carbon nanotubes
arXiv:0808.3251 · doi:10.1063/1.3093443
Abstract
We report a measurement on quantum capacitance of individual semiconducting and small band gap SWNTs. The observed quantum capacitance is remarkably smaller than that originating from density of states and it implies a strong electron correlation in SWNTs.
