title: Admittance of T-stub graphene nanoribbon structure.
abstract: In this work, we studied ac responses of T-stub structures that are composed of armchair and zigzag graphene ribbons. Compared with uniform graphene ribbons, the T-stub structures show extraordinary properties. The ac responses of armchair and zigzag T-stub structures show different behaviors for different edge configurations. The imaginary part of admittance can be capacitive or inductive depending on the Fermi energy and structural parameters. These properties provide deeper understanding of dynamic processes of electrons in graphene-based nanodevices.
