Abstract
Using a new device resembling a nano-CCD, and measuring the Coulomb blockade, we identify a new parameter, the "barrier capacitance". We then show how this parameter can be used to learn about the underlying shape of the energy barrier under a gate with a size of a few tens of nm. We observe Coulomb blockade in a device without energy barriers, where the conduction is via diffusive transport; we speculate on the cause of this observation.Citation
