Negative Quantum Capacitance Induced by Midgap States in Single-layer Graphene

Negative Quantum Capacitance Induced by Midgap States in Single-layer Graphene

We demonstrate that single-layer graphene (SLG) decorated with a high density of Ag adatoms displays the unconventional phenomenon of negative quantum capacitance. The Ag adatoms act as resonant impurities and form nearly dispersionless resonant impurity bands near the charge neutrality point (CNP)....
