Electric-Field-Induced Second Harmonic Generation at a Reconfigurable LaAlO/SrTiO Nanojunction
Pubudu Wijesinghe, Melanie Dieterlen, Kyoungjun Lee +5
Electrically tunable nonlinear optical responses at the nanoscale remain challenging to achieve because conventional nonlinear materials lack the combination of large susceptibilit…
Imaging GHz surface acoustic wave modes in electrostricted LaAlO/SrTiO heterostructures
Ranjani Ramachandran, Sayanwita Biswas, Prithwijit Mandal +6
The LaAlO/SrTiO (LAO/STO) interface hosts a gate-tunable superconducting two-dimensional electron gas (2DEG) which can be programmed to create quantum devices such as balli…
Local probing of superconductivity at oxide interfaces with atomic force microscopy
Dilek Yildiz, Sungmin Kim, Dengyu Yang +10
Superconductivity in strontium titanate has remained enigmatic for more than 50 years. The LaAlO/SrTiO (LAO/STO) heterointerface enables systematic dimensional confinement,…
Enhanced Superconductivity at Quantum-Critical KTaO3 Interfaces
Jieun Kim, Muqing Yu, Ahmed Omran +6
Superconductivity at oxide interfaces has intrigued researchers for decades, yet the underlying pairing mechanism remains elusive. Here we demonstrate that proximity to a ferroelec…
KTaO3-Based Supercurrent Diode
Muqing Yu, Jieun Kim, Ahmed Omran +7
The supercurrent diode effect (SDE), characterized by nonreciprocal critical currents, represents a promising building block for future dissipationless electronics and quantum circ…
Metal-organic Pulsed Laser Deposition for Complex Oxide Heterostructures
Jung-Woo Lee, Jieun Kim, Anthony L. Edgeton +21
Point defects in complex oxide thin films play a critical role in determining material properties but remain challenging to control with precision. This study introduces metal-orga…
