Perovskites—any material with the same structure as calcium titanium oxide (CaTiO3) —continue to entice materials scientists with their ferroelectricity, ferromagnetism, catalytic activity, and oxygen-ion conductivity. In recent years, scientists realized that they could vastly improve the properties of perovskites by assembling them into thin films. The problem was that no one understood why thin films beat out bulk materials.
