First-Principles Study on Various Point Defects Formed by Hydrogen and Helium Atoms in Tungsten
The different point defects formed by two hydrogen atoms or two helium atoms in tungsten were investigated through first-principles calculation. The energetically favorable site for a hydrogen atom is tetrahedral interstitial site while substitutional site is the most preferred site for a helium ato...
