Abstract
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 Å 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.Keywords
