Intervalley Scattering and the Role of Indirect Band Gap AlAs Barriers : Application to GaAs / AlGaAs Quantum Cascade Lasers


We report on the results of our simulations of Γ−X scattering in GaAs/AlGaAs heterostructures, discussing the importance of the mole fraction, doping density, and lattice and electron temperature in determining the scattering rates. We consider three systems, a single quantum well (for the investigation of Γ−X scattering), a double quantum well (to compare… (More)
