Ferroelastic twin wall mediated ferro-flexoelectricity and bulk photovoltaic effect in SrTiO
Ri He, Haowei Xu, Peijun Yang +3
Ferroelastic twin walls in nonpolar materials can give rise to a spontaneous polarization due to symmetry breaking. Nevertheless, the bi-stable polarity of twin walls and its rever…
