Abstract(in English) | A shear horizontal type surface acoustic wave (SH-SAW) propagates at liquid/solid interface without energy leakage to the liquid. This device can detect changes in conductivity and viscosity of liquid. c-axis parallel oriented ZnO film can be one of the best candidates for the SH-SAW liquid sensor on various substrates. Theoretical investigation of K^2 value in IDT/ZnO (0°, 90°, ψ) film/silica glass substrate structure showed that maximum value of K^2=3.4 % was found ψ=55° with H/λ=0.21. In this study, we fabricated these structures and evaluated K^2 values. Finally, excitations of SH-SAW were performed in the liquid. |
