Simultaneous effects of hydrostatic pressure and applied electric field on the impurity-related self-polarization in GaAs/Ga1−xAlxAs multiple quantum wells

► Impurity binding energy and self-polarization have a conjugate behavior in MQWs. ► Binding energy (self-polarization) is an increasing (decreasing) function of HP. ► For on-center impurity, the binding energy decreases with EF. ► For on-center impurity the self-polarization increases with EF.
