Polar vortices discovered in lead-free superlattices on silicon

A research team at HZB has reported the first observation of polar vortices in (BaTiO₃/SrTiO₃)₁₀ superlattices grown on silicon. This discovery broadens the types of materials and substrates that can host polar topological textures and suggests new possibilities for integrating complex ferroelectric states into silicon-based technologies.
