Effects of hydrostatic pressure on Pb(Zr1−xTix)O3 near the morphotropic phase boundary
A first-principles-derived effective Hamiltonian is adopted to simulate the effects of high-pressure on Pb(Zr1−xTix)O3 near the morphotropic phase boundary. With increasing pressure, the induced tetragonal-to-monoclinic and monoclinic-to-rhombohedral phase transitions are observed at low temperature...

Zusammenfassung: | A first-principles-derived effective Hamiltonian is adopted to simulate the effects of high-pressure on Pb(Zr1−xTix)O3 near the morphotropic phase boundary. With increasing pressure, the induced tetragonal-to-monoclinic and monoclinic-to-rhombohedral phase transitions are observed at low temperatures, which are accompanied by significantly enhanced piezoelectric responses. By determining the pressure-temperature phase diagram, it was revealed that the M phase resides in a narrow region between the T and R phases with inclining boundaries. |
