Heterogeneous diffusion and remnant hardening with excellent electromechanical compatibility in alkaline niobate composites† Both low mechanical losses and large piezoelectric coefficient (d33) are essential in high-power piezoelectric applications. However, achieving both a large d33 and a high mechanical quality factor (Qm) is generally considered challenging due to the inherent trade-off between these properties.
