Impurity induced disordering of strained GaP-GaAs1−xPx(x∼0.6) superlattices

Abstract
Data are presented showing that Zn diffusion into a strained GaP‐GaAs1−xPx (x∼0.6) superlattice (40 periods, Lz∼120 Å GaAsP quantum wells, LB∼120 Å GaP barriers) enhances the interdiffusion of As and P (anion interchange) at the heteriointerfaces, thus resulting in disordered indirect gap bulk crystal GaAs1−xPx (x∼0.8).
