  • Ab initio lattice dynamics of Ag(110) 
    Narasimhan, Shobhana (Elsevier Science BV, 2002-01-10)
    The lattice dynamics of Ag(110) is investigated by performing ab initio calculations to obtain the bulk and surface interatomic force constants. The results from the ab initio results are used to parametrize a model ...
  • Reversed anisotropies and thermal contraction of fcc (110 ) surfaces 
    Narasimhan, Shobhana (American Physical Society, 2001-09-10)
    The observed anisotropies of surface vibrations for unreconstructed fcc metal (110) surfaces are often reversed from the “common sense” expectation; for example, atoms in the top layer have larger amplitudes of vibration ...
