Abstract: With the use of the model excluded any deformation at the contact of monolayer and substrate role of the interlayer coupling is considered. It is shown that this coupling leads to the increase of the phonons frequencies values. Role of the external pressure and temperature is shortly discussed.
Keywords: force constants, phonons, pressure, temperature.
