Universally enhanced superconductivity and coexisting ferroelectricity at oxide interfaces
Meng Zhang, Ming Qin, Yanqiu Sun +2
The coexistence of superconductivity and ferroelectricity is rare due to their conflicting requirements: superconductivity relies on free charge carriers, whereas ferroelectricity…
Superconducting quantum oscillations and anomalous negative magnetoresistance in a honeycomb nanopatterned oxide interface superconductor
Yishuai Wang, Siyuan Hong, Wenze Pan +2
The extremely low superfluid density and unprecedented tunability of oxide interface superconductors provide an ideal platform for studying fluctuations in two-dimensional supercon…
Air-stable lithiation engineering of for direct-bandgap multilayers
Qi Fu, Yichi Zhang, Jichuang Shen +9
Due to its sizable direct bandgap and strong light-matter interactions, the preparation of monolayer has attracted significant attention and intensive research e…
Surface charge writing and non-volatile control of superconductivity in LaAlO3/KTaO3(111) heterostructure
Siyuan Hong, Yanqiu Sun, Yuan Liu +2
The oxide interface between LaAlO3 and KTaO3(111) can host an electron gas that condenses into superconductivity at low temperatures. In this work, we demonstrate a local and non-v…
Emergence of high-temperature superconductivity at the interface of two Mott insulators
Lele Ju, Tianshuang Ren, Zhu Li +8
Interfacial superconductivity has manifested itself in various types of heterostructures: band insulator-band insulator, band insulator-Mott insulator, and Mott insulator-metal. We…
Growth, Electronic Structure and Superconductivity of Ultrathin Epitaxial CoSi2 Films
Yuan Fang, Ding Wang, Peng Li +14
We report growth, electronic structure and superconductivity of ultrathin epitaxial CoSi2 films on Si(111). At low coverages, preferred islands with 2, 5 and 6 monolayers height de…
Observation of two-dimensional superconductivity at the LaAlO3/KTaO3(110) heterointerface
Zheng Chen, Zhongran Liu, Yanqiu Sun +12
We report on the observation of a Tc ~0.9 K superconductivity at the interface between LaAlO3 film and the 5d transition-metal oxide KTaO3(110) single crystal. The interface shows…
