Abstract

Read online

Charged ferroelectric domain walls show promise for two-dimensional conduction, but their abundance within (Ca,Sr)3Ti2O7 crystals is poorly understood. Here, Huang et al. discover topology related domain structures in such materials, which reveal the rich nature of hybrid improper ferroelectricity.
