QUANTUM-WELLS; LOCALIZATION; ABSORPTION; DEPENDENCE AB Reflectance spectra of GaAs/Al0.3Ga0.7As disordered superlattices; (d-SL) are investigated. The experimental results are compared with; numerical simulations obtained by means of transfer matrix method. The; agreement between the measured spectra and the numerical calculations; indicate the validity of the model we used; confirming the existence of; a disordered-induced fine structure and the formation of sub-minibands; of localized states in d-SL. The temperature dependence of the; reflectance spectra evidenced an anomalous splitting of some features; near the band edge; caused by space charge separation.
