摘要：

The ground-state energies of both heavy-hole and light-hole excitons in a GaAs/Ga1-xAlxAs quantum well have been studied by taking into account the interaction of different optical phonon modes with the excitons. The exciton energies and the corrections to the effective masses are obtained as functions of the well width and the Al concentration. Numerical calculation shows the strong influences of different phonon modes on the exciton behaviour in a quantum well as well as their dependence on the well width and height.
