Fine structure of the lowest Landau level in suspended trilayer graphene
H. J. van Elferen, A. Veligura, N. Tombros +4
Magneto-transport experiments on ABC-stacked suspended trilayer graphene reveal a complete splitting of the twelve-fold degenerated lowest Landau level, and, in particular, the ope…
Quantized coexisting electrons and holes in graphene measured using temperature dependent magneto-transport
E. V. Kurganova, S. Wiedmann, A. J. M. Giesbers +6
We present temperature-dependent magneto-transport experiments around the charge neutrality point in graphene and determine the amplitude of potential fluctuations responsible…
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…
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…
Quantum Hall activation gaps in bilayer graphene
E. V. Kurganova, A. J. M. Giesbers, R. V. Gorbachev +4
We have measured the quantum Hall activation gaps in bilayer graphene at filling factors and in high magnetic fields up to 30 T. We find that energy levels can be…
Generation of energy selective excitations in quantum Hall edge states
C. Leicht, P. Mirovsky, B. Kaestner +7
We operate an on-demand source of single electrons in high perpendicular magnetic fields up to 30T, corresponding to a filling factor below 1/3. The device extracts and emits singl…
Constructive role of non-adiabaticity for quantized charge pumping
B. Kaestner, C. Leicht, P. Mirovsky +5
We investigate a recently developed scheme for quantized charge pumping based on single-parameter modulation. The device was realized in an AlGaAl-GaAs gated nanowire. It has been…
