DOI: 10.1002/adma.202518326
Abstract: Topologically polar structures offer a rich landscape for uncovering emergent phenomena inaccessible in traditional ferroelectric materials. In contrast to the numerous examples found in ferroelectric oxides, topological structures identified in ferroelectric polymers are extremely rare.… read more here.
