Low-temperature epitaxial regrowth of ion-implanted amorphous GaAs

Abstract
Glancing‐angle Rutherford backscattering and channeling techniques have been used to investigate the regrowth of Ar+‐ion‐implanted amorphous layers on (100) GaAs. Under carefully controlled implant conditions, amorphous GaAs layers can be recrystallized epitaxially at temperatures below 250 °C. However, the regrowth process is complex, with the crystalline quality and regrowth rate most dependent on implant dose.
