Structure determination of an adsorbate-induced multilayer reconstruction: (1×2)-H/Ni(110).
In: Physical Review Letters, Vol. 58, No. 2: pp. 148-151
The reconstructed (1×2) structure formed by saturation of a Ni(110) surface with adsorbed H atoms at T<180 K was investigated by LEED. Excellent agreement between experimental and calculated I-V spectra for eleven nonequivalent beams was obtained for a model in which parallel rows of Ni atoms in the topmost layer are laterally shifted by 0.3 Å (‘‘row pairing’’) and which exhibits periodic vertical displacements (‘‘buckling’’) of the atoms in the second layer.
