Effects of Chemical and Structural Disorder in Semiconducting Pseudobinary Alloys

Abstract
The effects of both random chemical and bond-length variations on the electronic structure of zinc-blende pseudobinary alloys are treated within a realistic self-consistent effective-medium theory. Calculations for In1xGaxAs indicate that the effects of structural disorder are comparable in magnitude to those of chemical disorder and together they can either enhance or diminish the total scattering in a particular energy region.
