Graphene-based Quantum Dots: Fabrication and Properties

摘要

An approach to fabricate graphene-based quantum dots (QDs) by reconnecting the electroburned nanogap is demonstrated. The structure and electrical properties of graphene QDs were studied in detail. We also investigated the characteristics of Coulomb oscillation and Coulomb diamond, and estimated the value of charging energy. This work reveals that graphene nanogap is robust structure and may have a possible application in quantum dot systems.
