摘要：
Vibrational properties of the small tetrahedral cluster of Co on the Cu (111) surface are studied by using tightbinding second moment approximation interatomic interaction potentials. It was shown that interaction of the clusters with substrate leads to arising of frustrated translation and frustrated rotation in- plane polarized vibrational modes localized on the cluster atoms. The Co-4 cluster on the surface the high frequency modes remain strongly localized and mixed with the nearest neighbor atoms vibrations.
