On the persistence of polar domains in ultrathin ferroelectric capacitors
Pavlo Zubko, Haidong Lu, Chung-Wung Bark +5
The instability of ferroelectric ordering in ultra-thin films is one of the most important fundamental issues pertaining realization of a number of electronic devices with enhanced…
Tunable Band gap of Iron-Doped Lanthanum-Modified Bismuth Titanate Synthesized by the Thermal Decomposition of a Secondary Phase
Jun Young Han, Chung Wung Bark
The photoelectric properties of complex oxides have prompted interest in materials with a tunable band gap, because the absorption The substitution of iron atoms in La-modified bis…
Nonlocal Piezoresponse of LaAlO3/SrTiO3 Heterostructures
Mengchen Huang, Feng Bi, Chung-Wung Bark +4
The hysteretic piezoelectric response in LaAlO3/SrTiO3 heterostructures can provide important insights into the mechanism for interfacial conductance and its metastability under va…
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…
Tailoring a two-dimensional electron gas at the LaAlO3/SrTiO3 (001) interface by epitaxial strain
C. W. Bark, D. A. Felker, Y. Wang +9
Recently a metallic state was discovered at the interface between insulating oxides, most notably LaAlO3 and SrTiO3. Properties of this two-dimensional electron gas (2DEG) have att…
