Vertical polarization steered sideways in ultrathin ferroelectrics

Nature News & Views summarizes Gupta et al.'s finding that a thin-film ferroelectric couples vertical polarization to in-plane polarization, enabling small voltages to switch and stabilize large polarization using standard device geometry and potentially overcoming surface-polarization instability in ultrathin films for chip-compatible memories.

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.
