Evidence against the polarization rotation model of piezoelectric perovskites at the morphotropic phase boundary
Johannes Frantti, Yukari Fujioka, Risto M. Nieminen
The origin of the very large piezoelectric response observed in the vicinity of the morphotropic phase boundary (MPB) in perovskite lead zirconate titanate and related systems has…

Computational study of (111) epitaxially strained ferroelectric perovskites BaTiO3 and PbTiO3
Riku Oja, Karen Johnston, Johannes Frantti +1
The phase transition behaviour of PbTiO3 and BaTiO3 under (111) epitaxial strain is investigated using density-functional theory calculations. From tensile strains of +0.015 to com…
