Fast detection of single-charge tunneling to a graphene quantum dot in a
multi-level regime    [PDF]

In situ tunable radio-frequency charge detection is used for the determination of the tunneling rates into and out of a graphene single quantum dot connected to only one lead. An analytical model for calculating these rates in the multi-level tunneling regime is presented and found to correspond very well to our experimental observations.
