Long-Distance Diffusion of Excitons in Double Quantum Well Structures

Defect Induced Diffusion Mechanisms in Ion Implanted Quantum Well Structures

The present paper describes a method for utilizing X-ray diiraction measurements to determine the diiusion constant D associated with a speciic diffusion mechanism. In particular, for Cd 1?x Mn x Te quantum well structures a value of D 0:5 A 2 s ?1 was obtained for a vacancy controlled diiusion process.

Trapping of cold excitons in quantum well structures with laser light.

Optical trapping and manipulation of neutral particles has led to a variety of experiments from stretching DNA-molecules to trapping and cooling of neutral atoms. An exciting recent outgrowth of the technique is an experimental implementation of atom Bose-Einstein condensation. In this Letter, we propose and demonstrate laser-induced trapping for a new system--a gas of excitons in quantum well ...

Theory of Quantum Well Excitons in Electric and Magnetic Fields

The effects of external electric and magnetic fields on excitons in GaAsIAlGaAs quantum wells have been calculated in the effective mass approximation. Recent experiments by Viiia et al. which identify exciton couplings induced by an electric field are satisfactorily explained by the effects of valence band mixing. The properties of magneto-excitons in quantum wells are also found to be charact...
