Query: Charge detection in a bilayer graphene quantum dot   We show measurements on a bilayer graphene quantum dot with an integrated
charge detector. The focus lies on enabling charge detection with a 30 nm wide
bilayer graphene nanoribbon located approximately 35 nm next to a bilayer
graphene quantum dot with an island diameter of about 100 nm. Local resonances
in the nanoribbon can be successfully used to detect individual charging events
in the dot even in regimes where the quantum dot Coulomb peaks cannot be
measured by conventional techniques.
