| Zusammenfassung: | The dispersion law and density of states of phonons in ultrathin films was analyzed in
this paper. It turned out that phonons in a thin film require activation energy for exciting. This leads
to extremely low specific heat and specific conductivity at low temperatures. Consequences of
quoted facts were discussed in detail and their influence on kinetic and thermodynamic properties of
thin films is estimated. |
