Abstract
The embedded-atom method has been combined with Monte Carlo simulations to study the structure and order-disorder transformation of Au and Pt (110) surfaces. We find that the missing-row structure of Au disorders at 570 K, in close agreement with the experimental value of 650 K. For Pt, we predict a transformation at 750 K. Relaxations and vibrations are found to be essential for the accurate calculation of the critical temperature.Keywords
