Abstract: Ferroelectric charged domain walls (CDWs) with nanoscale thickness and bound charges are typically viewed as ultrathin, reconfigurable, and highly conductive two-dimensional components for domain wall nanoelectronics. Dimensional confinement of such polar topological structures has the potential to increase device density and unlock novel functionalities. We report 180° head-to-head and tail-to-tail CDWs exhibiting one-dimensional (1D) characteristics. These 1D CDWs are confined within the polar layers of ferroelectric ZrO2 and have atomic-scale dimensions in both width and thickness. Quantitative analysis unveils a distinct screening mechanism of these walls whereby bound polarization charges are compensated by self-balancing oxygen occupancy. We demonstrate electric field–driven manipulation of these 1D CDWs, revealing the microscopic coupling between polarization switching and oxygen-ion transport. Editor's summary: Freestanding ferroelectric zirconium dioxide thin films exhibit one-dimensional charged domain walls (1D CDWs) with head-to-head and tail-to-tail polarization. Zhong et al. imaged these 5-nanometer films and found that an alternating arrangement of nonpolar and polar oxygen ions formed 2D polar sheets that confined the 1D CDWs. Electric-field manipulation of these domain walls led to transport of oxygen ions. —Phil Szuromi [ABSTRACT FROM AUTHOR]
