Abstract :
We calculated the exciton binding energy and energy levels in GaAs/Al0.3Ga0.7As DQWs with non-abrupt interfaces, taking into account the electric and magnetic field effects. Numerical results for GaAs/Al0.3Ga0.7As double quantum wells show an enhancement of the e–hh exciton energy by as much as View the MathML source with respect to the abrupt well system (View the MathML source wide) when a View the MathML source interface is considered.
