本实验利用TDPAC方法,通过30MeVα粒子束(2μA)引起的~(109)Ag(α,2n)~(111)In核反应产生的~(111)In离子,研究了~(111)In离子在Ag中反冲引起的重离子辐射损伤. 实验结果表明在α粒子剂量率4.2×10~(12)cm~(-2)s~(-1)情况下,即使在室温环境中,仍引起明显的重离子辐射损伤.这些损伤破坏了Ag立方晶体结构的对称性而产生一个高达10~(18)V/cm~2的电场梯度作用于~(111)Cd探针核.并说明其是双空位或空位环俘获~(111)Cd的结果.实验还进行了激光退火效应的研究,指出其与真空热退火相比的优越性.
In this study, the ~ (111) In ions generated by ~ (109) Ag (α, 2n) ~ (111) In nuclei induced by 30MeVα particle beam (2μA) In the case of 4.2 × 10 ~ (12) cm ~ (-2) s ~ (-1) of α particles, even at room temperature environment, Heavy ion radiation damage.These damage damage the symmetry of the Ag cubic crystal structure and produce a gradient of electric field up to10-18V / cm ~ 2 on ~ (111) Cd probe nucleus.It shows that it is a double vacancy Or vacancy loop capture of the results of ~ (111) Cd.The experiment also conducted a laser annealing effect, pointed out that its vacuum thermal annealing compared to the superiority.
