Strong Aharonov-Bohm quantum interference in simply-connected LaAlO/SrTiO structures
Patrick Irvin, Hyungwoo Lee, Jung-Woo Lee +9
We report Aharonov-Bohm (AB)-type quantum interference in simply-connected devices created at the LaAlO/SrTiO interface using conductive-atomic force microscope (c-AFM) lit…
Shubnikov-de Haas-like Quantum Oscillations in Artificial One-Dimensional LaAlO3/SrTiO3 Electron Channels
Guanglei Cheng, Anil Annadi, Shicheng Lu +6
The widely reported magnetoresistance oscillations in LaAlO3/SrTiO3 heterostructures have invariably been attributed to the Shubnikov-de Haas (SdH) effect, despite a pronounced inc…
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…
Quantized Ballistic Transport of Electrons and Electron Pairs in LaAlO/SrTiO Nanowires
Anil Annadi, Guanglei Cheng, Shicheng Lu +10
SrTiO-based heterointerfaces support quasi-two-dimensional (2D) electron systems that are analogous to III-V semiconductor heterostructures, but also possess superconducting, m…
Micrometer-scale ballistic transport of electron pairs in LaAlO3/SrTiO3 nanowires
Michelle Tomczyk, Guanglei Cheng, Hyungwoo Lee +8
High-mobility complex-oxide heterostructures and nanostructures offer new opportunities for extending the paradigm of quantum transport beyond the realm of traditional III-V or car…
Current-driven spin orbit field in LaAlO3/SrTiO3 heterostructures
Kulothungasagaran Narayanapillai, Kalon Gopinadhan, Xuepeng Qiu +4
We demonstrate a current tunable Rashba spin orbit interaction in LaAlO3/SrTiO3 (LAO/STO) quasi two dimensional electron gas (2DEG) system. Anisotropic magnetoresistance (AMR) meas…
Gate Tunable In- and Out-Of-Plane Spin-Orbit Coupling and Spin Splitting Anisotropy at LaAlO3/SrTiO3 (110) Interface
Kalon Gopinadhan, A. Annadi, Younghyun Kim +6
Manipulating spin-orbit coupling (SOC) is important for devices such as spin-orbit torque based memory and its understanding is neccessary to answer several fundamental open questi…
Tailoring the electronic properties of SrRuO3 films in SrRuO3/LaAlO3 superlattices
Z. Q. Liu, M. Yang, W. M. Lü +10
The electronic properties of SrRuO3/LaAlO3 (SRO/LAO) superlattices with different interlayer thicknesses of SRO layers were studied. As the thickness of SRO layers is reduced, the…
Strong electronic correlation and strain effects at the interfaces between polar and nonpolar complex oxides
A. Annadi, A. Putra, Z. Q. Liu +6
The interface between the polar LaAlO and nonpolar SrTiO layers has been shown to exhibit various electronic and magnetic phases such as two dimensional electron gas, super…
Atomically flat interface between a single-terminated LaAlO3 substrate and SrTiO3 thin film is insulating
Z. Q. Liu, Z. Huang, W. M. Lü +5
The surface termination of (100)-oriented LaAlO3 (LAO) single crystals was examined by atomic force microscopy and optimized to produce a single-terminated atomically flat surface…
Reversible metal-insulator transition in LaAlO3 thin films mediated by intragap defects: An alternative mechanism for resistive switching
Z. Q. Liu, D. P. Leusink, W. M. Lü +13
We report on the electric-field-induced reversible metal-insulator transition (MIT) of the insulating LaAlO3 thin films observed in metal/LaAlO3/Nb-SrTiO3 heterostructures. The swi…
Nonlinear Insulator in Complex Oxides
Z. Q. Liu, D. P. Leusink, W. M. Lü +10
The insulating state is one of the most basic electronic phases in condensed matter. This state is characterised by an energy gap for electronic excitations that makes an insulator…
