Incipient ferroelectricity in methylammonium lead halide perovskites

Abstract Lead halide perovskites are promising materials for optoelectronic applications. Ferroelectricity is often considered as a phenomenon that improves their properties. However, the very existence of ferroelectricity in these materials is still debatable. Here we investigate the dielectric and...
