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…

Absence of localized electrons in KTaO interface superconductors
Xinqiang Cai, Jungho Kim, Leonardo Martinelli +19
Recently, an exciting discovery of orientation-dependent superconductivity was made in two-dimensional electron gas (2DEG) at the interfaces of LaAlO/KTaO (LAO/KTO) or EuO/…

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…
