“…Both MEAM and ECT predict contractions in the first two interlayers and expansion in the third interlayer for Cu(210). The results are also consistent with experiment and theory for Al(210) 24 and Pt(210), 25 which all point to significant inward surface relaxation resulting in smoothening of the corrugated (210) surface for fcc metals. The atoms on the rough surface change their bulk equilibrium positions, thereby minimizing the surface free energy, maximizing coordination number within the surface layer and thus bringing about a smoother surface.…”

High-index copper surfaces generally show a strong tendency to reconstruct, forming one-or even two-dimensional periodic nanostructures. In this paper, a survey will be presented of the various oxygen-induced reconstructions reported on high-index copper surfaces. In particular, the reconstructions of the Cu(210)-O system are presented, as revealed by low-energy electron diffraction (LEED) and scanning tunnelling microscopy (STM). The adsorption of oxygen leads to a series of (n × 1) (n = 4, 3, 2) surface reconstructions, the Cu (210)

The surface structure of Bi͑111͒ was investigated by low-energy electron diffraction ͑LEED͒ intensity analysis for temperatures between 140 and 313 K and by first-principles calculations. The diffraction pattern reveals a ͑1 ϫ 1͒ surface structure and LEED intensity versus energy simulations confirm that the crystal is terminated with a Bi bilayer. Excellent agreement is obtained between the calculated and measured diffraction intensities in the whole temperature range. The first interlayer spacing shows no significant relaxation at any temperature while the second interlayer spacing expands slightly. The Debye temperatures deduced from the optimized atomic vibrational amplitudes for the two topmost layers are found to be significantly lower than in the bulk. The experimental results for the relaxations agree well with those of our first-principles calculation.
