The origin of incipient ferroelectricity in lead telluride

The origin of incipient ferroelectricity in lead telluride

Group IV–VI materials often exist in a state near an electronic or structural phase transition. Here, the authors use ultrafast X-ray scattering to show that coupling of band-edge electrons and phonons causes the ferroelectric instability observed in lead telluride.
