Magneto-Stark effect on exciton in parabolic bandGaAs/〖Ga〗_(0.7) 〖Al〗_(0.3) As quantum well heterostructure

The effect of applied crossed electric and magnetic fields on the heterostructure semiconductor is used in the scientific investigation on electronic and optical exciton properties. The aim of this work is to study the magneto-Stark effect for confined excitons in single GaAs-〖Ga〗_(0.7) 〖Al〗_(0.3) As QWs. The magnetic field B is taken as perpendicular to the z-growth direction of the heterostructure, whereas the...
