Microwave HBAR spectroscopy and transducer application of carbon nanotube films

Abstract

The BAW spectroscopy method for the acoustic characterization of carbon nanotubes was applied. The material density and the elastic constants for carbon nanotube films were evaluated directly. The effect of the increase in the electric field near the electrodes with nanotube thin films may be conveniently used in electrostatic transducers for acoustic wave excitation in nonpiezoelectric solids and liquids.
