Direct Imaging of Sketched Conductive Nanostructures at the LaAlO3/SrTiO3 Interface
Zhanzhi Jiang, Xiaoyu Wu, Hyungwoo Lee +6
Nanoscale control of the quasi-two-dimensional electron gas at the LaAlO3/SrTiO3 (LAO/STO) interface by a conductive probe tip has triggered the development of a number of electron…
One-Dimensional Nature of Pairing and Superconductivity at the LaAlO/SrTiO Interface
Yun-Yi Pai, Hyungwoo Lee, Jung-Woo Lee +8
We examine superconductivity in LaAlO/SrTiO channels in which the channel width transitions from the 1D to 2D regime. The superconducting critical current is independent of…
Long-range non-Coulombic electron-electron interactions between coupled LaAlO/SrTiO nanowires
Yuhe Tang, Anthony Tylan-Tyler, Hyungwoo Lee +5
The LaAlO/SrTiO system exhibits unusual magnetic and superconducting behavior arising from electron-electron interactions whose physical origin is not well understood. Quan…
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…
Graphene-Complex-oxide Nanoscale Device Concepts
Giriraj Jnawali, Hyungwoo Lee, Jung-Woo Lee +9
The integration of graphene with complex-oxide heterostructures such as LaAlO/SrTiO offers the opportunity to combine the multifunctional properties of an oxide interface w…
