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…
Non-linear spin Seebeck effect due to spin-charge interaction in graphene
I. J. Vera-Marun, V. Ranjan, B. J. van Wees
The abilities to inject and detect spin carriers are fundamental for research on transport and manipulation of spin information. Pure electronic spin currents have been recently st…
Nonlinear interaction of spin and charge currents in graphene
I. J. Vera-Marun, V. Ranjan, B. J. van Wees
We describe a nonlinear interaction between charge currents and spin currents which arises from the energy dependence of the conductivity. This allows nonmagnetic contacts to be us…
