Skyrmions and merons in ferroic materials are topological structures with real-space swirling arrangements of order parameters. While current-driven motion of spin textures in magnets as nanoscale information carriers very little demonstrated with their electric dipolar counterparts, which in ferroelectric heterostructures In part, this is because their motion does not couple to uniform external fields as for the magnetic case, but instead couples to field gradients. As the polar textures are intrinsically nm-scale, developing imaging and control methods for exploring the stability and response of such particle-like objects to external stimuli at these length scales is of importance for the realization of logic devices. topological dipolar textures created by using the electric-field of a localized current, by the electron of scanning transmission
