Intrinsic stacking-fault energies and free energies were deduced from molecular dynamics simulations by using Cleri-Rosato empirical tight-binding potentials. The results exhibited significant deviations from experimental data, but the relative values for other elements remained correct. This permitted the use of the potentials for qualitative comparisons between metals with high and low stacking-fault energies. The effect of stacking faults upon the local vibrational properties near to the fault was examined, and it was found that the stacking fault had its strongest effect on modes in the center of the transverse peak. Its effect was localized to within a region of about 8 monolayers around the defect.
