abstract = "In this work, we study the silicon amorphization dependence on the crystal depth induced by 6-MeV Al2+ ions implanted in the LT 110 GT and randomly oriented silicon crystal channels, which was not directly experimentally accessible in the previous similar high-energy ioncrystal implantation cases. Accordingly, the micro-Raman spectroscopy scanning measurements along the crystal transversal cross section of the ion implanted region were performed. The ion fluence was 10(17) particles/cm(2). The scanning steps were 0.2 and 0.3 mu m, for the channeling and random ion implantations, respectively. The obtained results are compared with the corresponding Rutherford backscattering spectra of 1.2-MeV protons in the random and channeling orientations measured during the channeling implantation. Additionally, scanning electron microscope picture was taken on the transversal cross section of the implanted region in the channeling implantation case. We show here that the obtained silicon amorphization maxima are in excellent agreement with the corresponding estimated maxima of the aluminum concentration in silicon. This clearly indicates that the used specific micro-Raman spectroscopy scanning technique can be successfully applied for the depth profiling of the crystal amorphization induced by high-energy ion implantation.",
