摘要: Photoluminescence and absorption data are presented on Al x Ga1−x As‐GaAs superlattices(SLs) disordered into bulk‐crystal y Ga1−y As (0≤y≤x) by Si or Gediffusion. The produced impurity‐induced disordering (by Al‐Ga interchange) is determined transmission electron microscopy, measurements, photoluminescence to be homogeneous, with an alloy composition (y) that agrees the average concentration of SL. For low enough (y≊0.23
