    Surface and volume diffusion of niobium atoms on wolfram surface (110)
    (Azerbaijan National Academy of Sciences Institute of Radiation Problems ve Turkish Atomic Energy Authority, 2006) Imanbekov, Zh. Zh.; Imanbekova, T. D.; Bölüm Yok
    Diffusion properties of niobium atoms at the surface (110) of tungsten monocrystall were studied measuring electron work function φ and Auger-electron spectroscopy. Hurst-Gauss model which considers “traps” capturing for short time the diffusing atoms was taken for description of volume diffusion of Nb atoms in W subsurface. Based on the determined coefficient DΔ for Nb volume diffusion into W, surface diffusion has been described within Fisher model in terms of “suction” of migrating atoms perpendicularly to the surface of interest.
