摘要：

The existence of sharp resonant phonons in a slab separated from its semi-infinite substrate by a buffer layer is reported here. These resonant phonons appear as well-defined peaks in the phonon density of states. Such sharp resonant phonons are obtained here by a Green's function method both in the continuum elastic and in atomic approaches.
