摘要: The authors present the Brillouin spectra obtained from 22-tricosenoic acid, deposited onto a silicon substrate using Langmuir-Blodgett technique, for hypersound propagation both parallel and perpendicular to dipping direction. show expected elastic anisotropy of films also demonstrate that velocities increase with deposition surface pressure. Elastic constants are film at pressure 47.5+or-2.5 mN m-1 by fitting velocity data model film.
