英文摘要	The behaviour of the optical interface phonon in the graded quantum well (GQW) of AlxGa1-xAs with infinite Al0.4Ga0.6As barrier layers is investigated based on the dielectric continuum model. The solutions of the optical interface phonon modes are obtained. The perturbation theory is developed for kL << 1. It is found that the properties of the optical interface phonon in the GQW for kL << 1 are quite different from those in the square quantum well (SQW), as are those of GaAs-type modes from those of AlAs-type ones.
