ABSTRACT
Data are presented showing that layer disordering of Al[sub x] Gap[sub 1-x] As-GaAs quantum well heterostructures (QWH's) or superlattices (SL's) via ion implantation can be effected with a lattice constituent (Al), an inert ion (Kr), or an active impurity (Zn, Si, S, etc.). A doping impurity that diffuses (during annealing) via multiple sites, making column III sites available for Al-Ga interchange, is most effective in layer disordering. However, any implanted ion is itself relatively effective in converting an Al[sub x]Ga[sub 1-x]As-GaAs QWH or SL to bulk-crystal Al[sub y] Ga[sub 1-y] As (0 ≤ y ≤ x) via damage-induced disordering.
