Abstract

We report the results of molecular-dynamics simulations on oriented fcc thin films. For thin films of (001) orientation we found that independent of the potential, the intrinsic structural instability of these films governed their elastic properties. All of the in-plane elastic constants increase with decreasing film thickness for thin (111) films modeled with use of embedded-atom-method potentials, whereas (111) films modeled with use of a Lennard-Jones potential gave entirely opposite results.
