The inherently absent 2-dimensional electron gas in ultra-pure GaN/AlGaN heterostructures
S. Schmult, S. Wirth, V. V. Solovyev +5
Gallium nitride (GaN) has emerged as an essential semiconductor material for energy-efficient lighting and electronic applications owing to its large direct bandgap of 3.4 eV. Pres…
Artificially constructed plasmaron and plasmon-exciton molecule in 2D-metals
A. S. Zhuravlev, V. A. Kuznetsov, V. E. Bisti +3
Resonant optical excitation was used to create a macroscopic non-equilibrium ensemble of dark excitons with unprecedentedly long lifetime in a two-dimensional (2D) electron system…
Light-hole quantization in the optical response of ultrawide GaAs/AlGaAs quantum wells
V. V. Solovyev, V. A. Bunakov, S. Schmult +1
Temperature-dependent reflectivity and photoluminescence spectra are studied for undoped ultra-wide 150 nm and 250 nm GaAs quantum wells. It is shown that spectral features previou…
Nonlinear growth with the microwave intensity in radiation-induced magnetoresistance oscillations
R. G. Mani, C. Gerl, S. Schmult +2
We report the observation of inverse-magnetic-field-periodic, radiation-induced magnetoresistance oscillations in GaAs/AlGaAs heterostructures prepared in W. Wegscheider's group, c…
Extra Spin-Wave mode in Quantum Hall systems. Beyond the Skyrmion Limit
I. K. Drozdov, L. V. Kulik, A. S. Zhuravlev +4
We report on the observation of a new spin mode in a quantum Hall system in the vicinity of odd electron filling factors under experimental conditions excluding the possibility of…
Interlayer tunneling in counterflow experiments on the excitonic condensate in quantum Hall bilayers
Y. Yoon, L. Tiemann, S. Schmult +2
The effect of tunneling on the transport properties of} quantum Hall double layers in the regime of the excitonic condensate at total filling factor one is studied in counterflow e…
