Ion Beam Synthesis of Silicon Carbide: Infra-Red and RBS Studies


We report on p-SiC thin layer synthesis by carbon ion implantation at high temperature. Infra-red and RBS analysis were performed on samples implanted at temperatures ranging from 200 to 900°C and for carbon doses varying in the range 1017to2.1018 cm. RBS analysis does not reveal any diffusion or segregation of carbon up to 900°C. At this temperature we obtained the optimum Infra-red signature. The (3-SiC formation is shown to be a thermally activated process with an energy of 0.1 eV leading us to speculate that the diffusion of point defects could be the limiting factor of the process.
