AbstractResults from simulations of Ni, Al, Ni3Al, and NiAl show long-range, oscillatory surface relaxations that decay exponentially into the bulk. Pure fcc Ni and Al have oscillation periods that are close to the nearest-neighbor distance, independent of crystal face. This is shown to be due to surface smoothing and steric effects. In Ni3Al and NiAl, the surface planes are rippled, with the Ni-Ni and Al-Al interlayer spacings oscillating 180°out of phase. Very good agreement between our results and experimentally measured atomic relaxations is obtained. © 1986 The American Physical Society.
