Hafnia Confirms Antiferroelectricity Strengthens at 0.6-Nanometer Monolayer, Overturning Decades-Old Physics Prediction

Researchers at the University of Nebraska–Lincoln and Washington University in St. Louis have shown that hafnium oxide remains intrinsically antiferroelectric down to a single-atom monolayer, with the effect growing stronger rather than weaker as the material thins.
