20-year-old puzzle solved: Physicists reveal the ‘three-dimensional vortex’ of zero-dimensional ferroelectricity
Researchers from KAIST, in collaboration with multiple institutions, have experimentally confirmed the three-dimensional vortex-shaped polarization distribution in ferroelectric nanoparticles. Using atomic electron tomography, they mapped atomic positions in barium titanate nanoparticles and calculated the internal polarization distribution. This finding confirms theoretical predictions from two decades ago and holds potential for the development of ultra-high-density memory … Read more
