Wave-like domain walls drive polarization switching in sliding ferroelectrics, study finds

Sliding ferroelectrics are a type of two-dimensional (2D) material realized by stacking nonpolar monolayers (atom-thick layers that lack an electric dipole). When these individual layers are stacked, they produce ferroelectric ...
