Hw. Alberts et al., CHANNELING AND TEM INVESTIGATIONS OF PULSE ELECTRON-BEAM ANNEALED GAAS IMPLANTED WITH PB, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 80-1, 1993, pp. 519-522
GaAs single crystals were implanted at room temperature with 150 keV P
b ions with doses ranging from 1 x 10(12) to 5 x 10(16) ions cm-2. The
amorphous surface layer of a crystal implanted with a dose of 1 x 10(
15) cm-2 was subjected to pulsed electron beam annealing (PEBA) at ene
rgy densities up to 0.84 J cm-2. The damaged and recrystallized crysta
ls were analyzed with backscattering and channeling of 2.0 MeV alpha-p
articles. The channeling results were correlated with those obtained w
ith TEM investigations.
