Charged domain boundaries stabilized by translational symmetry breaking in the hybrid improper ferroelectric Ca3–x Sr x Ti2O7

Charged domain walls in ferroelectrics are interesting as they may enhance electrical conductivity. Here, atomic-resolution imaging of Ca3–xSrxTi2O7 reveals that charged domain boundaries are stabilized by an out-of-phase translational shift of crystallographic domains and that Sr ions accumulate at...
