摘要: 用蒙特卡罗方法计算不同几何结构的双层重金属对有机半导体界面产生的剂量增强系数, 结果表明, X射线在金-酞菁铜-金界面产生与金-酞菁铜界面相似但更大的剂量增强. 当半导体层-酞菁铜厚度相同(均为2 μm)时, 厚度为4 μm比厚度为2 μm的金产生更大的剂量增强; 当金的厚度相同(均为2 μm)时, 厚度为1 μm比厚度为2 μm的酞菁铜产生更大的剂量增强. 

Abstract: The dose-enhancement-factors of different structure Au-CuPc-Au were calculated by Monte-Carlo method. The results show the dose-enhancement-factors of Au-CuPc-Au are simailer to that of Au-CuPc, but it has larger dose-enhancement-factors than those of Au-CuPc. Under the circumstance (the thickness of CuPc is 2 μm), the dose-enhancement-factor of 4 μm gold is larger than that of 2 μm gold. Under the circumstance (the thickness of gold is 2 μm), the dose-enhancement-factor of 1 μm CuPc is larger than that of 2 μm CuPc.

Key words: X-ray, organic semiconductor, dose-enhancement-factor, interface
