Rippled Moire Superlattices for Decoupled Ferroelectric Bits
Di Fan, Changming Ke, Shi Liu
Symmetry considerations suggest that moire superlattices formed by twisted two-dimensional materials should preserve overall inversion symmetry. However, experiments consistently r…

Superlubric Motion of Wave-like Domain Walls in Sliding Ferroelectrics
Changming Ke, Fucai Liu, Shi Liu
Sliding ferroelectrics constructed from stacked nonpolar monolayers enable out-of-plane polarization in two dimensions with exceptional properties, including ultrafast switching sp…
