| 摘 要： | 基于重离子和脉冲激光与Si材料相互作用的机理分析,提出了脉冲激光能量等效重离子LET的等效判据。该判据认为:如果半导体材料每吸收1个光子就能产生1个载流子,则脉冲激光和重离子诱发1个载流子所需的能量是等效的。利用该等效判据及Beer定律,推导出线性吸收条件下脉冲激光能量与重离子LET之间等效换算公式。本工作计算的脉冲激光能量等效LET结果与国外文献结果一致。

| Abstract: | Based on the analysis of the interaction between heavy ion as well as pulsed laser and silicon materials,a criterion for a pulsed laser energy equivalent linear energy transfer (LET) was presented. The criterion assumes that if each absorbed photon can generate a carrier in semiconductor materials,the energy to generate a carrier induced by pulsed laser and heavy ion is equivalent. Using this criterion and Beer's law,an equivalent conversion formula between pulsed laser energy and heavy-ion LET under linear... |
