The height of swelling structures produced by the Ar^+ beam is much higher than that produced by the C^+ beam at energy 90 keV with the fluence up to 8 × 10^<16>/cm^2. The large different in the swelling height was well understood base on the productivity of vacancies evaluated by the SRIM simulation and experiment. Post-implantation samples irradiated with fluence 4 × 10^<16>/cm^2, were annealed at various temperatures in the range of 200 ~ 800 ℃. In the case of Ar^+ irradiated samples, the swelling height started to increase at about 600 ℃. In contrast, in the case of C^+ beam irradiated samples, the swelling height started to decrease at about 600 ℃ and almost disappeared at 800 ℃. The opposite behavior is understood based on the difference in irradiation-induced defect and in rearrangement mechanism in the thermal annealing process.}, pages = {17--20}, title = {Swelling and annealing phenomena of Si crystal irradiated by Ar and C ion beams}, volume = {282}, year = {2012} }
