摘要：

We show that the conduction-band minimum in a (GaAs)1/(AlAs)1 superlattice derives from the X(x,y) minimum of bulk AlAs, not from L of GaAs as predicted by many theoretical calculations. This is shown by the sign of the shift in the low-temperature photoluminescence under [001] stress, by the relative magnitudes of the shifts under [100] and [110] stress, by the phonon sidebands, and by the observation of a splitting under [100] but not under [110] stress.
