Pressure-Induced Anomalous Phase Transitions and Colossal Enhancement of Piezoelectricity in PbTiO
Zhigang Wu, Ronald E. Cohen
We find an unexpected tetragonal-to-monoclinic-to-rhombohedral-to-cubic phase transition sequence induced by pressure, and a morphotropic phase boundary in a pure compound using fi…

Ab initio linear response and frozen phonons for the relaxor PMN (PbMg1/3Nb2/3O3)
Narayani Choudhury, Zhigang Wu, E. J. Walter +1
We report first principles density functional studies using plane wave basis sets and pseudopotentials and all electron linear augmented plane wave (LAPW) of the relative stability…
