Physicists Solve 20-Year-Old Puzzle of Zero-Dimensional Ferroelectrics

Researchers at KAIST and collaborators have experimentally confirmed the three-dimensional vortex-shaped polarization distribution inside ferroelectric nanoparticles using atomic electron tomography. This breakthrough, which validates 20-year-old theoretical predictions, could lead to the development of ultra-high-density memory devices capable of storing significantly more data than current technologies.
