Scaling Of The Coulomb Energy Due To Quantum Fluctuations In The Charge Of A Quantum Dot
arXiv:cond-mat/9503135 · doi:10.1103/PhysRevLett.75.4282
Abstract
The charging energy of a quantum dot is measured through the effect of its potential on the conductance of a second dot. This technique allows a measurement of the scaling of the dot's charging energy with the conductance of the tunnel barriers leading to the dot. We find that the charging energy scales quadratically with the reflection probability of the barriers. In a second experiment we study the transition from a single to a double-dot which exhibits a scaling behavior linear in the reflection probability. The observed power-laws agree with a recent theory.
