Scaling of the Coulomb blockade

Research output: Contribution to journalJournal articleResearchpeer-review

We describe two experiments to study the influence of fluctuations in the electron charge on the transport properties of a quantum dot. First, we scan a device from single-to double quantum-dot behavior by varying the conductance of a connecting point contact. Second, we measure the dependence of the charging energy on the conductance of the barriers. The experiments are compared with traces obtained from a modeling that assumes a scaling behavior of the charging energy. Good agreement is obtained.
