Experimental Band Structure of Pb(Zr,Ti)O : Mechanism of Ferroelectric Stabilization.

Pb(Zr,Ti)O (PZT) is the most common ferroelectric (FE) material widely used in solid-state technology. Despite intense studies of PZT over decades, its intrinsic band structure, electron energy depending on 3D momentum k, is still unknown. Here, Pb(Zr Ti )O using soft-X-ray angle-resolved photoelectron spectroscopy (ARPES) is explored.

Photoelectron spectroscopy studies of (001) oriented PbTi0.8Zr0.2O3 (PZT) single crystal layers with submicron resolution revealed areas with different Pb 5d binding energies, attributed to the different charge and polarization states of the film surface.
