Quantum Hall transport as a probe of capacitance profile at graphene edges
I. J. Vera-Marun, P. J. Zomer, A. Veligura +6
The quantum Hall effect is a remarkable manifestation of quantized transport in a two-dimensional electron gas. Given its technological relevance, it is important to understand its…
Field induced quantum-Hall ferromagnetism in suspended bilayer graphene
H. J. van Elferen, A. Veligura, E. V. Kurganova +5
We have measured the magneto-resistance of freely suspended high-mobility bilayer graphene. For magnetic fields T we observe the opening of a field induced gap at the charge…
Relating Hysteresis and Electrochemistry in Graphene Field Effect Transistors
Alina Veligura, Paul J. Zomer, Ivan J. Vera-Marun +3
Hysteresis and commonly observed p-doping of graphene based field effect transistors (FET) was already discussed in reports over last few years. However, the interpretation of expe…
Coexistence of electron and hole transport in graphene
S. Wiedmann, H. J. van Elferen, E. V. Kurganova +8
When sweeping the carrier concentration in monolayer graphene through the charge neutrality point, the experimentally measured Hall resistivity shows a smooth zero crossing. Using…
Spin splitting in graphene studied by means of tilted magnetic-field experiments
E. V. Kurganova, H. J. van Elferen, A. McCollam +6
We have measured the spin splitting in single-layer and bilayer graphene by means of tilted magnetic field experiments. Applying the Lifshitz-Kosevich formula for the spin-induced…
Quantized conductance of a suspended graphene nanoconstriction
Nikolaos Tombros, Alina Veligura, Juliane Junesch +4
A yet unexplored area in graphene electronics is the field of quantum ballistic transport through graphene nanostructures. Recent developments in the preparation of high mobility g…
