摘要:

We have studied photoluminescence of direct‐gap and ‘‘indirect‐gap’’ GaAs‐AlAs superlattices under electric field perpendicular to the layers. In the former case, the quantum confined Stark effect is observed as expected. In the latter case, reverse effects are found, providing evidence thatX‐like electron states are confined in the AlAs slabs.
