Single electron current sources have generated great interest because of their potential applications in quantum computing and in electrical metrology. In particular, a reliable single electron pump can be used to redefine the Ampere in terms of the electron charge and a known frequency, thus allowing the closing of the quantum metrological triangle. The demonstration of record high accuracy of the Quantum Hall Effect in silicon carbide epitaxial graphene1 has already made it a prime candidate as a quantum resistance standard, thus taking us one step closer to an all graphene closure of the quantum metrological triangle. In this workshop, I will talk about our work on graphene double quantum dot charge pumps, and characterizing quantum Hall transport in silicon carbide epitaxial graphene.
