摘要：
We report magneto-exciton spectroscopy studies of(411)A and (100)-oriented GaAs/Al0.3Ga0.7As multiquantum well structures. The samples consisted of seven GaAs quantum wells with widths varying between 0.6 and 12nm, were grown on (411)A and (100)-oriented GaAs substrates. The exciton diamagnetic energy shifts and linewidths were measured between 0 and 14T at 1.4K The dependence of the exciton diamagnetic shifts with magnetic field were calculated using a variational approach and good agreement with experiment for both substrate orientations was found. Within experimental error, the conduction band masses for both the (100) and (411)A-oriented structures are nearly the same.
