Center Researchers identify the Ferroelectric Nematic Phase (June 2020)
Center researchers have identified a liquid crystal that has the long sought-after ferroelectric nematic phase. Ferroelectric behavior has been observed previously in tilted chiral smectics and in bent-core smectics but a polar nematic phase has proven elusive for more than 100 years. The ferroelectric nematic responds readily to applied electric fields and displays a host of novel electrooptic and hydrodynamic properties. (6/20)
