Researchers have demonstrated a new technique for precisely controlling phase boundaries in thin film materials by manipulating the thickness of those films—allowing them to engineer energy storage materials that do not rely on toxic elements. In proof-of-concept testing for the new technique, the researchers found that a nontoxic thin film has extremely promising dielectric properties, raising the possibility of creating new capacitor technologies that don’t rely on toxic materials.
