Softening of the optical phonon by reduced interatomic bonding strength without depolarization

Nature, Published online: 30 October 2024; doi:10.1038/s41586-024-08099-0An alternative route to drive the transverse optical phonon softening sheds light on developing a unified theory for ferroelectricity enhancement in ultrathin films free from depolarization fields using ionic radius differences and strains, among... #press
