Author(s): Hongwei Wang, Gan Jin, Minzhi Dai, Er Pan, Baomin Wang, Changming Ke, Shi Liu, Ri He, and Run-Wei Li Sliding ferroelectrics possess vertical polarization via stackings of monolayer van der Waals (vdW) materials, exhibiting energy efficiency and ultrafast switching dynamics. Here, we uncover an intriguing polarization-switching behavior in bilayer BN, wherein the interlayer sliding is locked toward … [Phys. Rev. Lett. 137, 126801] Published Tue Sep 15, 2026
