SUMMARY:Towards Single-electron Pumping with Graphene Quantum Hall Antidot

DESCRIPTION:The accurate redefinition of the basic SI unit\, the Ampere\, 
 in terms of the fundamental elementary charge\, e\, is important and meani
 ngful in the area of quantum metrology. Single-electron pumping can genera
 te an electric current\, which provides a powerful tool in the research of
  metrology.\n\nThis work presents a new idea for the realization of a fast
  and accurate quantized charge pumping technology with graphene quantum an
 tidots.  It reviews literatures on single-electron pumping metrology backg
 round\, quantum Hall antidots and graphene unique properties making it a p
 romising material to realize antidots single-electron pumps\, specifically
  in relation to future work in our group. In addition\, design\, fabricati
 on and basic experiment methods are introduced. Finally\, some results on 
 current progress towards the goal of single-electron charge pumping with g
 raphene quantum Hall antidots are also reported.
