Dynamical control over the confinement of spatially indirect excitons in electrostatic traps of GaAs coupled quantum wells

Mussie Beian, Suzanne Dang, Mathieu Alloing +6

We study spatially indirect excitons confined in a 10 $\mu$m wide electrostatic trap of a GaAs double quantum well. We introduce a technique to control the amplitude of the electric…
