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…
Magnetic field tuned superconductor-to-insulator transition at the LaAlO /SrTiO interface
M. M. Mehta, D. A. Dikin, C. W. Bark +4
We present a study of the magnetic field tuned superconductor-to-insulator transition (SIT) in the electron gas that forms at the LaAlO/SrTiO interface. We find that the ma…
Room-Temperature Electronically-Controlled Ferromagnetism at the LaAlO3/SrTiO3 Interface
Feng Bi, Mengchen Huang, Chung-Wung Bark +4
Reports of emergent conductivity, superconductivity, and magnetism at oxide interfaces have helped to fuel intense interest in their rich physics and technological potential. Here…
Anomalous Transport in Sketched Nanostructures at the LaAlO3/SrTiO3 Interface
Guanglei Cheng, Joshua P. Veazey, Patrick Irvin +10
The oxide heterostructure LaAlO3/SrTiO3 supports a two-dimensional electron liquid with a variety of competing phases including magnetism, superconductivity and weak antilocalizati…
Electro-Mechanical Response of Top-Gated LaAlO3/SrTiO3 Heterostructures
Feng Bi, Mengchen Huang, Chung Wung Bark +5
LaAlO3/SrTiO3 heterostructures are known to exhibit a sharp, hysteretic metal-insulator transition (MIT) with large enhanced capacitance near depletion. To understand the physical…
