Abstract
We present the anharmonicity and roughening of cu surfaces derived fro m the derivatives of the layer spacings and the surface energies with respect temperature using the embedded-atom molecular dynamics method. The anharmonicity and roughening of the Cu(110) surface stared to inc rease rapidly around 600 K and 1000 K respectively. In addition, we pr esent the dependence of th surface energy on the temperature of the he teroepitaxial Au/Ag(110) system. The slope of the surface energy was f ound to be less pronounced compared with that of the free Ag(110) surf ace system.
