Polarity control of carrier injection at ferroelectric/metal interfaces for electrically switchable diode and photovoltaic effects
Daesu Lee, S. H. Baek, T. H. Kim +4
We investigated a switchable ferroelectric diode effect and its physical mechanism in Pt/BiFeO3/SrRuO3 thin-film capacitors. Our results of electrical measurements support that, ne…
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…
Nature of polarization fatigue in BiFeO3
Seung-Hyub Baek, Chad M. Folkman, Jae-Wan Park +4
As a room-temperature multiferroic, BiFeO3 has been intensively investigated for both magnetoelectric devices and non-volatile ferroelectric memory applications. Both magnetoelectr…
