Novel Transformations of PbTiO3 with Pressure and Temperature
Husam Farraj, Stefano Racioppi, Gaston Garbarino +8
We investigated the behavior of lead titanate (PbTiO3) up to 100 GPa, both at room temperature and upon laser heating, using synchrotron X ray diffraction combined with density fun…

Absence of high pressure ground state re-entrant ferroelectricity in PbTiO
R. E. Cohen, Yangzheng Lin, Muhtar Ahart +1
We study ferroelectricity in the classic perovskite ferroelectric PbTiO to high pressures with density functional theory (DFT) and experimental diamond-anvil techniques. We use…
