Atomic imaging of mechanically induced topological transition of ferroelectric vortices
Abstract Ferroelectric vortices formed through complex latticeācharge interactions have great potential in applications for future nanoelectronics such as memories. For practical applications, it is crucial to manipulate these topological states under external stimuli. Here, we apply mechanical loads to locally manipulate the vortices in a PbTiO 3 /SrTiO 3 superlattice ā¦
