Giant Flexoelectric Effect in Ferroelectric Epitaxial Thin Films
Daesu Lee, A. Yoon, S. Y. Jang +5
We report on nanoscale strain gradients in ferroelectric HoMnO3 epitaxial thin films, resulting in a giant flexoelectric effect. Using grazing-incidence in-plane X-ray diffraction,…
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…
Initial growth behavior and resulting microstructural properties of heteroepitaxial ZnO thin films on sapphire (0001) substrates
C. Liu, S. H. Chang, T. W. Noh +5
We have investigated the initial growth behavior and resulting microstructural properties of heteroepitaxial ZnO thin films prepared by pulsed laser deposition on sapphire (0001) s…
Ferroelectric properties of SrRuO3/BaTiO3/SrRuO3 ultrathin film capacitors free from passive lay
Y. S. Kim, J. Y. Jo, D. J. Kim +9
Structural studies on ultrathin SrRuO3/BaTiO3/SrRuO3 capacitors, with BaTiO3 thicknesses of between 5 nm and 30 nm, show well-defined interfaces between ferroelectric BaTiO3 and el…
Formation of Co nanoclusters in epitaxial Ti_{0.96} Co_{0.04} O_2 thin films and their ferromagnetism
D. H. Kim, J. S. Yang, K. W. Lee +8
Anatase Ti0.96Co0.04O2 films were grown epitaxially on SrTiO3 (001) substrates by using plused laser deposition with in-situ reflection high-energy electron diffraction. The oxygen…
