The Hydrodynamic model has been discussed for the study of frequency of surface optical phonon coupled oscillations at the surface of different nano materials and this theory is applied to obtained the dispersion relation for semi-infinite single plane boundary [1]. The possibility of interaction of surface optical phono at different material’s surface has been discussed with the help of its dielectric functions at different mediums. A surface optical phonon mode can exist at the interface between the nanostructure and the surrounding medium, which is of primary interest in this work. The optical mode is dominated by oscillations from atoms at the surface of semiconducting materials. We use theoretical methods for the calculation of surface optical phonon frequency curve with respect to different mediums. The appearance of SOP waves of different materials has been observed in dispersive medium (Glass).
