Abstract
The AlAs/Al0.5Ga0.5As disordered superlattice is fabricated, and its photoluminescent properties are compared with those of Al0.76Ga0.24As bulk alloy and the (AlAs)2(Al0.5Ga0.5As)2 ordered superlattice. Their macroscopic AlAs compositions are almost the same, 0.75, but their microscopic structures are different. Among them, the AlAs/Al0.5Ga0.5As disordered superlattice exhibits the highest photoluminescent intensity at 4.2 K. A red shift is observed in a photoluminescent peak.Keywords
