金减缓铁中氦泡的生长
Gold slows down the growth of helium bubble in iron
摘要:
我们用第一性原理计算预言,在体心立方结构的Fe中,Au对He有很强的亲合力。在He气泡表面的分离Au层中的Au-Au键合比Fe-Fe和Au-Fe相互作用强;因此该层成为进一步He的有效屏障并减缓气泡生长。
英文摘要:
We predict by first-principles calculations that Au have strong affinity to He in bcc Fe. The Au-Au bonding in the segregated Au layer at the He bubble surface is stronger than Fe-Fe and Au-Fe interactions; therefore this layer becomes an effective barrier to further He and slows down the bubble growth.
