Structural evolution of bismuth sodium titanate induced by A-site non-stoichiometry: Neutron powder diffraction studies
I. -K. Jeong, Y. S. Sung, T. K. Song +2
We performed neutron powder diffraction measurements on (BiNa)TiO and (BiNa)TiO to study structural evolution induced by the non-stoichi…
Step bunching-induced vertical lattice mismatch and crystallographic tilt in vicinal BiFeO3(001) films
T. H. Kim, S. H. Baek, S. Y. Jang +7
Epitaxial (001) BiFeO3 thin films grown on vicinal SrTiO3 substrates are under large anisotropic stress from the substrates. The variations of the crystallographic tilt angle and t…
Domain Switching Kinetics in Disordered Ferroelectric Thin Films
J. Y. Jo, H. S. Han, J. -G. Yoon +3
We investigated domain kinetics by measuring the polarization switching behaviors of polycrystalline Pb(Zr,Ti)O films, which are widely used in ferroelectric memory devices.…
Polarization Switching Dynamics Governed by Thermodynamic Nucleation Process in Ultrathin Ferroelectric Films
J. Y. Jo, D. J. Kim, Y. S. Kim +4
A long standing problem of domain switching process - how domains nucleate - is examined in ultrathin ferroelectric films. We demonstrate that the large depolarization fields in ul…
Polarization Relaxation Induced by Depolarization Field in Ultrathin Ferroelectric BaTiO Capacitors
D. J. Kim, J. Y. Jo, Y. S. Kim +5
Time-dependent polarization relaxation behaviors induced by a depolarization field were investigated on high-quality ultrathin SrRuO/BaTiO/SrRuO capacitor…
