Table 1.

Comparison between the FBARs with different structures.

Electrode Geometry Crystal Orientation Field Intensity (V/m) * Electromechanical Coupling Mean Allan Deviation
Coplanar (lateral excited) Normal c-axis 1.73 0.32% 5.39 × 10−8
Sandwiched (thickness excited) Inclined c-axis 6.67 0.68% 1.61 × 10−8

* The applied voltage between the electrodes was 10 V for the calculation.
