At the University of Minnesota, researchers have discovered that the boundary between two materials — invisible to the naked eye, measurable only in nanometers — can be engineered to fundamentally alter how metals conduct electricity. By controlling the thickness of a ruthenium dioxide film with atomic precision, the team demonstrated that polarization, long thought to belong only to insulators, can be locked into a metallic system and used as a tuning mechanism for electronic behavior. This finding, published in Nature Communications, suggests that the atomic scale is not merely a frontier of
