Domain-Wall-Mediated Ultralow-Barrier Sliding and Pinning in Ferroelectric Moire Superlattices Revealed by Machine Learning

Abstract Sliding ferroelectrics built from stacked nonpolar monolayers enable out-of-plane polarization and unconventional switching via interlayer sliding, yet the microscopic sliding dynamics remain unclear. Using machine-learning molecular dynamics, we reveal spontaneous, ther...
