Researchers find coherent ferrons—polarization waves with potential across quantum and telecom applications
In new research published in Nature Materials, a team of researchers led by Columbia University chemist Xiaoyang Zhu, in collaboration with fellow Columbians Xavier Roy, Milan Delor, Dmitri Basov, and ...
Fig. 1 (a) Schematic of a PM that consists of two nanobeam cavities. (b) Normalized profile of the electric field (Ex at left and Ey at right) for the S and AS mode Polarization is an intrinsic ...
Sliding ferroelectrics are a type of two-dimensional (2D) material realized by stacking nonpolar monolayers (atom-thick layers that lack an electric dipole). When these individual layers are stacked, ...
A household refrigerator magnet has an inherent polarity, a characteristic it shares with other magnets of its kind, known as ferromagnets. Ferroelectric materials are also polarized — electrically ...
