摘要

C+-implanted GaAs that the surfaces were encapsulated with 2 x 10(20) cm(-3) As-doped a-Si:H films were annealed at temperatures of 850-1000 degrees C. Carriers were generated only in a shallower region than the projected range of the C+ ions, The sheet carrier concentrations increased slightly with the implanted dose. The activation of implanted C atoms in GaAs encapsulated with As-doped a-Si:H films was improved in comparison with Si or GaAs wafer proximity annealed GaAs and SiO2 encapsulation-annealed GaAs.
