我们报告的实验和模拟活动，旨在探索纳米多孔Au（NP-Au）泡沫的辐射响应。在不同的辐照剂量率下，我们发现了不同的缺陷积累行为。当np-Au泡沫在高剂量率下辐照时，形成层错四面体，但在低剂量率下，它们似乎不会在np-Au中形成。根据这些结果，提出了一个模型来解释剂量率依赖的缺陷积累。(C)2012年美国物理学会。[http：//dx.doi.org/10.1063/1.4764528]
We report on an experimental and simulation campaign aimed at exploring the radiation response of nanoporous Au (np-Au) foams. We find different defect accumulation behavior by varying radiation dose-rate in ion-irradiated np-Au foams. Stacking fault tetrahedra are formed when np-Au foams are irradiated at high dose-rate, but they do not seem to be formed in np-Au at low dose-rate irradiation. A model is proposed to explain the dose-rate dependent defect accumulation based on these results. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4764528]
