Conclusion
Herein, we have demonstrated a controllable nano-cracking in MnPt/PMN-PT heterostructures by applying a small in-plane voltage onto two separated electrodes. Based on such ferroelectric cracking, non-volatile switching of single-crack and complementary switching of two-crack were realized in a simple manner, combining the advantages of both NEM switch and ferroelectric. In addition, the complementary switching of cracks is mainly decided by the complementary Ez distribution. Finally, RL implemented by complementary switching of two cracks has been demonstrated. The current work unveils a unique device platform, giving rise to multiple energy-efficient and high-density integrated applications.
