Abstract
The effects of pulsed electron-beam annealing of high-dose As implanted {111} Si single crystals has been studied. The depth distributions and lattice location of the As atoms were obtained using MeV4He+ backscattering and channeling technique. The implantation energy was 100 keV with a total dose of 3.5·1016/cm2. Above the threshold energy of 0.9 J/cm2 the single-crystal transition was observed with about 95% of the As atoms on substitutional lattice sites. This leads to an As concentration of 2·1021/cm3 which was demonstrated to be a metastable one.
