Photoluminescence and stimulated emission in Si- and Ge-disordered Al/sub x/Ga/sub 1-x/As-GaAs superlattices
Journal Article
·
· J. Appl. Phys.; (United States)
Photoluminescence and absorption data are presented on Al/sub x/Ga/sub 1-x/As-GaAs superlattices (SLs) disordered into bulk-crystal Al/sub y/Ga/sub 1-y/As (0< or =y< or =x) by Si or Ge diffusion. The bulk-crystal Al/sub y/Ga/sub 1-y/As produced by impurity-induced disordering (by Al-Ga interchange) is determined by transmission electron microscopy, absorption measurements, and photoluminescence to be homogeneous, with an alloy composition (y) that agrees with the average Al concentration of the SL. For low enough Al concentration (yroughly-equal0.23
