Nonequilibrium transport in density-modulated phases of the second Landau level
S. Baer, C. Rössler, S. Hennel +5
We investigate non-equilibrium transport in the reentrant integer quantum Hall phases of the second Landau level. At high currents, we observe a transition from the reentrant integ…
Scanning-gate-induced effects and spatial mapping of a cavity
R. Steinacher, A. A. Kozikov, C. Rössler +4
Tailored electrostatic potentials are the foundation of scanning gate microscopy. We present several aspects of the tip-induced potential on the two-dimensional electron gas. First…
Experimental probe of topological orders and edge excitations in the second Landau level
Stephan Baer, Clemens Rössler, Thomas Ihn +3
We measure weak quasiparticle tunneling across a constriction in the second Landau level. At = 7/3, 8/3 and 5/2, comparison of temperature and DC bias dependence to weak tunnel…
Locally induced quantum interference in scanning gate experiments
A. A. Kozikov, R. Steinacher, C. Rössler +4
We present conductance measurements of a ballistic circular stadium influenced by a scanning gate. When the tip depletes the electron gas below, we observe very pronounced and regu…
Resonant electron tunneling in a tip-controlled potential landscape
N. Pascher, F. Timpu, C. Rossler +4
By placing the biased tip of an atomic force microscope at a specific position above a semiconductor surface we can locally shape the potential landscape. Inducing a local repulsiv…
