DESCRIPTION:Single electron current sources have generated great interest 
 because of their potential applications in quantum computing and in electr
 ical metrology. In particular\, a reliable single electron pump can be use
 d to redefine the Ampere in terms of the electron charge and a known frequ
 ency\, thus allowing the closing of the quantum metrological triangle. The
  demonstration of record high accuracy of the Quantum Hall Effect in silic
 on carbide epitaxial graphene[1]  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\, a
 nd characterizing quantum Hall transport in silicon carbide epitaxial grap
 hene.
