Abstract

Abstract : Brillouin scattering by anisotropic Langmuir–Blodgett (LB) films is studied here. The films are composed of behenic acid doped with CdS and CuS nanocrystals distributed in the matrix of the behenic acid. The sound velocities along and perpendicular to the film surface are determined. The influence of nanocrystals on the LB film anisotropy and sound velocities is discussed. Abstract : The Langmuir–Blodgett film composed of behenic acid molecules reveals anisotropic elastic properties for the sound waves propagated along and perpendicular to the film surface. Semiconductor nanocrystals embedded in the films reduce the anisotropy and change the elastic properties of the system.
