Physicists discover the “three-dimensional vortex” of zero-dimensional ferroelectrics
Researchers at KAIST, in collaboration with multiple institutions, have experimentally confirmed the three-dimensional distribution of vortex-shaped polarization inside ferroelectric nanoparticles. Using electron atomic tomography, they mapped the atomic positions in the barium titanate nanoparticles and calculated the internal polarization distribution. This discovery confirms theoretical predictions made 20 years ago and has potential for the development … Read more
