Aharonov-Bohm effect and coherence length of charge e/4 quasiparticles at 5/2 filling factor measured in multiple small Fabry-Perot interferometers
R. L. Willett, L. N. Pfeiffer, K. W. West +1
Design of a Fabry-Perot (double point contact) interferometer to measure fractional quantum Hall effect quasiparticle charge properties, and in particular the 5/2 excitations, pose…
Evidence of inter-layer interaction in magneto-luminescence spectra of electron bilayers
Ilirjan Aliaj, Vittorio Pellegrini, Andrea Gamucci +4
Magneto-luminescence studies in electron bilayers reveal the hallmarks of the even-denominator and other quantum Hall states in the intensities and energies of the inter-band optic…
Non-linear response of a high mobility two-dimensional electron system near the second harmonic of the cyclotron resonance
A. T. Hatke, M. A. Zudov, L. N. Pfeiffer +1
Recent experiments on microwave-irradiated high-mobility two-dimensional electron systems revealed a novel photoresistivity peak in the vicinity of the second cyclotron resonance h…
Spatially probed electron-electron scattering in a two-dimensional electron gas
M. P. Jura, M. Grobis, M. A. Topinka +3
Using scanning gate microscopy (SGM), we probe the scattering between a beam of electrons and a two-dimensional electron gas (2DEG) as a function of the beam's injection energy, an…
Role of electron-electron interactions in nonlinear transport in 2D electron systems
A. T. Hatke, M. A. Zudov, L. N. Pfeiffer +1
We study the temperature evolution of the non-linear oscillatory magnetoresistance in a high-mobility two-dimensional electron system subject to a strong dc electric field. We find…
Engineering artificial graphene in a two-dimensional electron gas
M. Gibertini, A. Singha, V. Pellegrini +5
At low energy, electrons in doped graphene sheets behave like massless Dirac fermions with a Fermi velocity which does not depend on carrier density. Here we show that modulating a…
