A Phase Diagram for Quantum Hall Bilayers with Strong Inter-layer Correlation
Biswajit Karmakar, Vittorio Pellegrini, Aron Pinczuk +2
Inter-layer excitonic coherence in a quantum Hall bilayer with negligible tunneling is monitored by measurements of low-lying spin excitations. At new quasiparticle excita…
Control of optical emission in doped GaAs/AlGaAs nanofabricated quantum dots
Sokratis Kalliakos, Cesar Pascual Garcia, Vittorio Pellegrini +8
Dilute arrays of GaAs/AlGaAs modulation-doped quantum dots (QDs) fabricated by electron-beam lithography and low impact reactive-ion etching exhibit highly homogeneous luminescence…
Electrostatic traps for dipolar excitons
Ronen Rapaport, Gang Chen, Steve Simon +3
We consider the design of two-dimensional electrostatic traps for dipolar indirect excitons. We show that the excitons dipole-dipole interaction, combined with the in-plane electri…
Strong photo-absorption by a single quantum wire in waveguide-transmission spectroscopy
Yasushi Takahashi, Yuhei Hayamizu, Hirotake Itoh +4
We measured the absorption spectrum of a single T-shaped, 14x6 nm lateral-sized quantum wire embedded in an optical waveguide using waveguide-transmission spectroscopy at 5 K. In s…
Dynamics of in-plane charge separation front in 2D electron-hole gas
Gang Chen, Ronen Rapaport, Steven H. Simon +2
We show both experimentally and theoretically that the recently observed optically induced in-plane charge separation in quantum well (QW) structures and the exciton ring emission…
Moving Beyond a Simple Model of Luminescence Rings in Quantum Well Structures
D. Snoke, S. Denev, Y. Liu +5
The dramatic appearance of luminescence rings with radius of several hundred microns in quantum well structures can be understood through a fairly simple nonlinear model of the dif…
