| 英文摘要 | In this work, we report the ultrahigh electromechanical coupling performance of NBT-6BT-KNN lead-free single crystal at room temperature. The thickness mode electromechanical coupling coefficient (k(t)) and the 31 mode electromechanical coupling coefficient (k(31)) reach 69.0% and 45.7%, respectively, which are superior to the PZT-5H lead-based ceramics ofk(t)similar to 60% andk(31)similar to 39%. In addition, the evolution of the crystal structure and domain morphology is revealed by Raman scattering spectra, a polarizing microscope and piezoelectric force microscopy characterization. |
