Atomic scale symmetry and polar nanoclusters in the paraelectric phase of ferroelectric materials
Andreja Bencan, Emad Oveisi, Sina Hashemizadeh +6
The nature of the "forbidden" local- and long-range polar order in nominally nonpolar paraelectric phases of ferroelectric materials has been an open question since the discovery o…
Role of charged defects on the electrical and electro-mechanical properties of rhombohedral Pb(Zr,Ti)O3 with oxygen octahedra tilts
Tadej Rojac, Silvo Drnovsek, Andreja Bencan +2
Oxygen octahedra tilting is a common structural phenomenon in perovskites and has been subject of intensive studies, particularly in rhombohedral Pb(Zr,Ti)O3 (PZT). Early reports s…
Piezoelectric nonlinearity and frequency dispersion of the direct piezoelectric response of BiFeO3 ceramics
Tadej Rojac, Andreja Bencan, Goran Drazic +2
We report on the frequency and stress dependence of the direct piezoelectric d33 coefficient in BiFeO3 ceramics. The measurements reveal considerable piezoelectric nonlinearity, i.…
