Mode specific backscattering in a quantum point contact
A. A. Kozikov, R. Steinacher, C. Rössler +4
We demonstrate a scanning gate grid measurement technique consisting in measuring the conductance of a quantum point contact (QPC) as a function of gate voltage at each tip positio…
Non-local polarization feedback in a fractional quantum Hall ferromagnet
Szymon Hennel, Beat A. Braem, Stephan Baer +11
In a quantum Hall ferromagnet, the spin polarization of the two-dimensional electron system can be dynamically transferred to nuclear spins in its vicinity through the hyperfine in…
Capacitive coupling in hybrid Graphene-GaAs nanostructures
Pauline Simonet, Clemens Rössler, Tobias Krähenmann +5
Coupled hybrid nanostructures are demonstrated using the combination of lithographically patterned graphene on top of a two-dimensional electron gas (2DEG) buried in a GaAs/AlGaAs…
Wave Physics of the Graphene Lattice Emulated in a Ripple Tank
J. Rössler, C. Rössler, P. Märki +2
Using the example of graphene, we have extended the classic ripple tank experiment to illustrate the behavior of waves in periodic lattices. A loudspeaker driving air through a per…
