摘要：
The anisotropic splitting of the exciton emission doublet, seen experimentally in a type-II GaAs/AlAs superlattice, is analyzed. The splitting is shown to result from nonconservation of the hole spin component normal to the boundary upon reflection from an ideal heterojunction, because of the low (C2v) of this junction.
