SEM and XRD results showed reaction time and KOH concentration affect crystal growth and grain size. Two dimensional finite element method (2DFEM) simulation was carried out prior to experiment and electromechanical coupling coefficient (k31) and mechanical quality factor (Qm) for different film thickness were calculated from simulation data.
