Observation of Quantum Capacitance of individual single walled carbon nanotubes [PDF]

open access: yes, 2008
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 ...
