Research at the ALS and Molecular Foundry showed that distortions in the structure of hafnium oxide surprisingly lead to enhanced ferroelectricity (reversible electric polarization) as it gets thinner (down to 1 nanometer). The work opens the door to novel ultrasmall, energy-efficient electronics. https://als.lbl.gov/unexpected-rise-in-ferroelectricity-as-material-thins/
