Random RBS spectra for the samples with fluences ranging from 0.4 × 1016to 3.4 × 1016 cm-2. Implantation current density is 2.0 μAcm-2. The dashed line is a guide for the eye for the shift of the depth profile with increasing fluence. The arrow labeled with Pb indicates the energy for backscattering from Pb atoms at the surface.
