摘要：

An improved two-band model is proposed for excitons in GaAs-Ga1-xAlxAs quantum wells, where the x dependence of the anisotropic effective masses and the dielectric mismatch are both included. Application to symmetric quantum wells shows consistent agreement with experiments. Exciton energies and oscillator strengths are given for a typical asymmetric quantum well.
