Chaotic Dirac billiard in graphene quantum dots
L. A. Ponomarenko, F. Schedin, M. I. Katsnelson +4
We report on transport characteristics of quantum dot devices etched entirely in graphene. At large sizes, they behave as conventional single-electron transistors, exhibiting perio…

Quantum-Hall activation gaps in graphene
A. J. M. Giesbers, U. Zeitler, M. I. Katsnelson +3
We have measured the quantum-Hall activation gaps in graphene at filling factors and for magnetic fields up to 32 T and temperatures from 4 K to 300 K. The gap ca…
