In-plane quasi-single-domain BaTiO via interfacial symmetry engineering
J. W. Lee, K. Eom, T. R. Paudel +18
The control of the in-plane domain evolution in ferroelectric thin films is not only critical to understanding ferroelectric phenomena but also to enabling functional device fabric…
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…
Unveiling the ac Dynamics of Ferroelectric Domains by Investigating the Frequency Dependence of Hysteresis Loops
S. M. Yang, J. Y. Jo, T. H. Kim +7
We investigated nonequilibrium domain wall dynamics under an ac field by measuring the hysteresis loops of epitaxial ferroelectric capacitors at various frequencies and temperature…
Electric-field-controlled directional growth of ferroelectric domains in multiferroic BiFeO3 films
T. H. Kim, S. -H. Baek, S. M. Yang +7
We describe the directional growth of ferroelectric domains in a multiferroic BiFeO3 thin film, which was grown epitaxially on a vicinal (001) SrTiO3 substrate. A detailed structur…
Emergent excitations in a geometrically frustrated magnet
S. -H. Lee, C. Broholm, W. Ratcliff +4
Frustrated systems are ubiquitous and interesting because their behavior is difficult to predict. Magnetism offers extreme examples in the form of spin lattices where all interacti…
