Transport in a three-terminal graphene quantum dot in the multi-level regime
Transport three-terminal graphene quantum dot the multi-level regime
2012/2/27
We investigate transport in a three-terminal graphene quantum dot. All nine elements of the conductance matrix have been independently measured. In the Coulomb blockade regime accurate measurements of...
