Spin Texture in a Cold Exciton Gas
A. A. High, A. T. Hammack, J. R. Leonard +5
We report on the observation of a spin texture in a cold exciton gas in a GaAs/AlGaAs coupled quantum well structure. The spin texture is observed around the exciton rings. The obs…

Excitons in Electrostatic Traps
A. T. Hammack, N. A. Gippius, G. O. Andreev +3
We consider in-plane electrostatic traps for indirect excitons in coupled quantum wells, where the traps are formed by a laterally modulated gate voltage. An intrinsic obstacle for…

Tunable spin polarization in III-V quantum wells with a ferromagnetic barrier
R. C. Myers, A. C. Gossard, D. D. Awschalom
We demonstrate the epitaxial growth of optical-quality electrically-gated III-V ferromagnetic quantum structures. Photoluminescence spectroscopy reveals that initially unpolarized…
