概要

• 論文の詳細を見る

• Waveguides provide several advantages such as acoustic and optical beam confinement, prolongation of delay time, and high acoustic intensity for the acoustic devices. Using proton exchange (PE) with benzoic acid, we have investigated the surface acoustic wave (SAW) properties of a PE waveguide using Z-cut LiNbO_3. With this tight energy confinement, the acoustic waveguide structure enables the guided SAW to be in a suitable mode for dilute electrolyte sensing. Furthermore, it is noteworthy that the dielectric constant of a PE layer can be deduced from the critical conductivity.
