Attenuation of surface acoustic waves by conducting Langmuir-Blodgett films of charge-transfer complexes (C16H33-TCNQ)0.4-(C17H35-DMTTF)0.6

The d.c. conductivity and attenuation of surface acoustic waves (SAW) have been measured in conducting LB films prepared by the vertical dipping method as a function of temperature. The large attenuation of SAW by the film is due to the electric field coupling loss in the film. The a.c. conductivity calculated from the attenuation data is compared with the d.c. conductivity
