Coulomb Gap in Graphene Nanoribbons
S. Dröscher, H. Knowles, Y. Meir +2
We investigate the density and temperature-dependent conductance of graphene nanoribbons with varying aspect ratio. Transport is dominated by a chain of quantum dots forming sponta…

Observation of excited states in a graphene double quantum dot
F. Molitor, H. Knowles, S. Dröscher +8
We study a graphene double quantum dot in different coupling regimes. Despite the strong capacitive coupling between the dots, the tunnel coupling is below the experimental resolut…
