- Title
Ferroelectrics: The positives of going negative.
- Authors
Schlom, Darrell G.; Fennie, Craig J.
- Abstract
The article discusses the report by Jin Wang and colleagues on the application of negative pressure to ferroelectric lead titanate (PbTiO3) to increase its spontaneous polarization and ferroelectric transition temperature. The authors created a stable phase PbTiO3 using a lower density, metastable polymorph of PbTiO3. Also provided are the features of the stable polymorph including the density and transition temperature.
