Orientation-dependent electron-phonon coupling in interfacial superconductors LaAlO3/KTaO3
Xiaoyang Chen, Tianlun Yu, Yuan Liu +17
The emergent superconductivity at the LaAlO3/KTaO3 interfaces exhibits a mysterious dependence on the KTaO3 crystallographic orientations. Here we show, by soft X-ray angle-resolve…
Magnetic and Electronic Properties of Single-Crystalline BaCoSO

P. K. Biswas, Z. Salman, Q. Song +6
Bulk FeSe is superconducting with a critical temperature 8 K and SrTiO is insulating in nature, yet high-temperature superconductivity has been reported at the in…
Anomalous correlation effects and unique phase diagram of electron doped FeSe revealed by angle resolved photoemission spectroscopy
C. H. P. Wen, H. C. Xu, C. Chen +9
In FeSe-derived superconductors, the lack of a systematic and clean control on the carrier concentration prevents the comprehensive understanding on the phase diagram and the inter…
