Analysis of Trapped Quantum Degenerate Dipolar Excitons
Ronen Rapaport, Gang Chen, Steven Simon
The dynamics of quantum degenerate two-dimensional dipolar excitons confined in electrostatic traps is analyzed and compared to recent experiments. The model results stress the imp…
Artificial trapping of a stable high-density dipolar exciton fluid
Gang Chen, Ronen Rapaport, L. N. Pffeifer +5
We present compelling experimental evidence for a successful electrostatic trapping of two-dimensional dipolar excitons that results in stable formation of a well confined, high-de…
Nonlinear dynamics of a dense two-dimensional dipolar exciton gas
Ronen Rapaport, Gang Chen, Steven H. Simon
We use a simple model to describe the nonlinear dynamics of a dense two dimensional dipolar exciton gas. The model predicts an initial fast expansion due to dipole-dipole pressure,…
Optical Gain from InAs Nanocrystal Quantum Dots in a Polymer Matrix
Gang Chen, Ronen Rapaport, Dan Fuchs +3
We report on the first observation of optical gain from InAs nanocrystal quantum dots emitting at 1.55 microns based on a three-beam, time resolved pump-probe technique. The nanocr…
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…
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…
