▎ 摘  要

We show measurements on a bilayer graphene quantum dot (QD) 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 QD 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 QD Coulomb peaks cannot be measured by conventional techniques.
