Structural and Conductive Changes of Alumina Ceramics and Silicon Crystal Implanted with High-Flux Ti Ion
95% Al2O3 ceramics and Si <100> crystal were implanted by Ti ion in a MEVVA implanter. The influence of implantation parameters was studied by varying ion fluence. The samples were implanted by 80 keV Ti ion with fluences from 1 x1015 to 1 x 1018 ions/cm2, respectively. The samples were investigated by SEM, SAM, and four-probe measurement. Differentmorphologies were observed on the surfaces of the samples due to irradiation damage, and clearly related to implantation parameters. XRD spectra confirm formation of titanium silicides on the surfaces of Si samples with ion fluences equal to or high than 1x1015 ions/cm2. The experimental results suggest that it is possible to synthesise titanium silicides by using a MEVVA implanter.
