It is shown that the main contribution to these characteristics is made by high-frequency optical modes, which are responsible for oscillations in the direction perpendicular to the plane of the layers, and the modes related to Jan-Teller instability in materials with phase transitions.  Product Description popup.authors Бабука Т.Я.
