Stark shifts for heavy-hole and light-hole levels in an isolated GaAs/AlGaAs quantum well have been analyzed by an exact numerical calculation within the envelope function approximation. The calculated results predict that for wells thicker than about 100 Ã… the Stark shift for heavy hole is larger than that for light hole; however, for thinner wells this tendency is reversed. It also predicts that this well size dependence strongly depends on the band offset ratio.
