Tuning inter-dot tunnel coupling of an etched graphene double quantum dot by adjacent metal gates

Graphene double quantum dots (DQDs) open to use charge or spin degrees of freedom for storing and manipulating quantum information in this new electronic material. However, impurities and edge disorders in etched graphene nano-structures hinder the ability to control the inter-dot tunnel coupling, t...
