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…

Double polarization hysteresis loop induced by the domain pinning by defect dipoles in HoMnO3 epitaxial thin films
Daesu Lee, Heung-Sik Kim, Seung Yup Jang +5
We report on antiferroelectriclike double polarization hysteresis loops in multiferroic HoMnO3 thin films below the ferroelectric Curie temperature. This intriguing phenomenon is a…
