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…

Anomalous sequence of quantum Hall liquids revealing tunable Lifshitz transition in bilayer graphene

Anastasia Varlet, Dominik Bischoff, Pauline Simonet +6

Fermi surface topology plays an important role in determining the electronic properties of metals. In bulk metals, the Fermi energy is not easily tunable at the energy scale needed…

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…

Dynamics of spin-flip photon-assisted tunneling

F. R. Braakman, J. Danon, L. R. Schreiber +2

We present time-resolved measurements of spin-flip photon-assisted tunneling and spin-flip relaxation in a doubly occupied double quantum dot. The photon-assisted excitation rate a…

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…

Magnetoresistance Induced by Rare Strong Scatterers in a High Mobility 2DEG

L. Bockhorn, I. V. Gornyi, D. Schuh +3

We observe a strong negative magnetoresistance at non-quantizing magnetic fields in a high-mobility two-dimensional electron gas (2DEG). This strong negative magnetoresistance cons…
