Collective electronic excitation in a trapped ensemble of photogenerated dipolar excitons and free holes revealed by inelastic light scattering
Sebastian Dietl, Sheng Wang, Dieter Schuh +5
Photogenerated excitonic ensembles confined in coupled GaAs quantum wells are probed by a complementary approach of emission spectroscopy and resonant inelastic light scattering. L…
Classical Stückelberg interferometry of a nanomechanical two-mode system at room temperature
Maximilian J. Seitner, Hugo Ribeiro, Johannes Kölbl +3
The transition from classical to quantum mechanics has intrigued scientists in the past and remains one of the most fundamental conceptual challenges in state-of-the-art physics. B…
Circuit Electromechanics with a Non-Metallized Nanobeam
Matthias Pernpeintner, Thomas Faust, Fredrik Hocke +4
We have realized a nano-electromechanical hybrid system consisting of a silicon nitride beam dielectrically coupled to a superconducting microwave resonator. We characterize the sa…
Signatures of two-level defects in the temperature-dependent damping of nanomechanical silicon nitride resonators
Thomas Faust, Johannes Rieger, Maximilian J. Seitner +2
The damping rates of high quality factor nanomechanical resonators are well beyond intrinsic limits. Here, we explore the underlying microscopic loss mechanisms by investigating th…
Single exciton emission from gate-defined quantum dots
G. J. Schinner, J. Repp, E. Schubert +6
With gate-defined electrostatic traps fabricated on a double quantum well we are able to realize an optically active and voltage-tunable quantum dot confining individual, long-livi…
Enlarged magnetic focusing radius of photoinduced ballistic currents
Markus Stallhofer, Christoph Kastl, Marcel Brändlein +5
We exploit GaAs-based quantum point contacts as mesoscopic detectors to analyze the ballistic flow of photogenerated electrons in a two-dimensional electron gas at a perpendicular…
