Gold slows down the growth of helium bubble in iron

Abstract
- 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.<br />Comment: 9 pages, 4 figures, 1 table
