Abstract

We report the results of calculations for multilayer and atomic relaxations around steps on Cu(210), using many-body interaction potential extracted from the embedded atom method (EAM). Relaxations are found to extend several layers into the bulk with an oscillatory behavior of (-,-,+,-,+,+)• Unlike the recent low energy electron diffraction (LEED) data, the calculated multilayer relaxations reveal a nonuniform damping magnitudes in interlayer relaxations. We, furthermore, investigate the local atomic relaxations around steps and trace the changes, relative to the bulk, to the modifications in the associated local force fields.
