Controlled nano-cracking actuated by an in-plane voltage

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 E z 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.
