Abstract
Using the method of two-time dependent Green's functions applying to bounded and translational perturbed systems, the phonon spectra and thermodynamic characteristic of film-structures and superlattice are analyzed. Free and internal energy of the system as well as specific heat and entropy are found. The temperature behavior of layered structures specific heat is compared to that of bulk-structures.
