Electronic-grade epitaxial (111) KTaO3 heterostructures
Jieun Kim, Muqing Yu, Jung-Woo Lee +13
KTaO3 has recently attracted attention as a model system to study the interplay of quantum paraelectricity, spin-orbit coupling, and superconductivity. However, the high and low va…
Nanoscale control of LaAlO3/SrTiO3 metal-insulator transition using ultra-low-voltage electron-beam lithography
Dengyu Yang, Shan Hao, Jun Chen +8
We describe a method to control the insulator-metal transition at the LaAlO3/SrTiO3 interface using ultra-low-voltage electron beam lithography (ULV-EBL). Compared with previous re…
Engineered spin-orbit interactions in LaAlO/SrTiO-based 1D serpentine electron waveguides
Megan Briggeman, Jianan Li, Mengchen Huang +6
The quest to understand, design, and synthesize new forms of quantum matter guides much of contemporary research in condensed matter physics. One-dimensional (1D) electronic system…
One-dimensional Kronig-Penney superlattices at the LaAlO/SrTiO interface
Megan Briggeman, Hyungwoo Lee, Jung-Woo Lee +9
The paradigm of electrons interacting with a periodic lattice potential is central to solid-state physics. Semiconductor heterostructures and ultracold neutral atomic lattices capt…
Frictional drag between superconducting LaAlO/SrTiO nanowires
Yuhe Tang, Jung-Woo Lee, Anthony Tylan-Tyler +6
We report frictional drag measurements between two superconducting LaAlO/SrTiO nanowires. In these experiments, current passing through one nanowire induces a voltage acros…
Gate-Tunable Optical Nonlinearities and Extinction in Graphene/LaAlO/SrTiO Nanostructures
Erin Sheridan, Lu Chen, Jianan Li +7
Pristine, undoped graphene has a constant absorption of 2.3 % across the visible to near-infrared (VIS-NIR) region of the electromagnetic spectrum. Under certain conditions, such a…
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…

Megan Briggeman, Michelle Tomczyk, Binbin Tian +10
The ability to create and investigate composite fermionic phases opens new avenues for the investigation of strongly correlated quantum matter. We report the experimental observati…
Reconfigurable edge-state engineering in graphene using LaAlO/SrTiO nanostructures
Jianan Li, Qing Guo, Lu Chen +9
The properties of graphene depend sensitively on doping with respect to the charge-neutrality point (CNP). Tuning the CNP usually requires electrical gating or chemical doping. Her…
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…

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…
