Optical Investigation of Coupled GaAs/Al0.3Ga0.7As Double Quantum Wells Separated by AIAs Barriers
Electronically symmetric coupled double quantum wells are structures where two quantum wells are separated by a thin barrier layer. Both experiment and theory show that when the barrier is so narrow that there...

Excitons in the Two-Dimensional Hole Gas at the Al0.5Ga0.5As/GaAs Interface
Radiative recombination processes associated with the A1xGa1-xAs/GaAs heterojunction interface have been intensively studied recently. Yuan et al. [1] first observed the PL line on the low energy side of the GaAs...
