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…
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…
Surface acoustic wave generation and detection in quantum paraelectric regime of SrTiO-based heterostructure
Dengyu Yang, Muqing Yu, Yun-Yi Pai +5
Strontium titanate (STO), apart from being a ubiquitous substrate for complex-oxide heterostructures, possesses a multitude of strongly-coupled electronic and mechanical properties…
Electron Pairing and Nematicity in LaAlO/SrTiO Nanostructures
Aditi Nethwewala, Hyungwoo Lee, Jianan Li +6
Strongly correlated electronic systems exhibit a wealth of unconventional behavior stemming from strong electron-electron interactions. The LaAlO/SrTiO (LAO/STO) heterostru…
Quantum Coherence Tomography of Lightwave Controlled Superconductivity
