Constraining the Superconducting Gap of Monolayer FeSe/SrTiO via Statistical Analysis and Tip-Height-Dependent Tunneling Spectroscopy
Dongwon Shin, Xiyou Peng, Kaleb McClure +6
Monolayer FeSe grown on SrTiO (001) exemplifies interface-enhanced superconductivity, exhibiting a transition temperature nearly ten times that of bulk FeSe. Yet, its tunneling…

Fingerprinting superconductors by disentangling Andreev and quasiparticle currents across tunable tunnel junctions
Petro Maksymovych, Sang Yong Song, Benjamin Lawrie +2
Tunneling Andreev reflection (TAR) spectroscopy offers a powerful new approach to fingerprint superconducting pairing symmetry at the atomic scale. By leveraging the exponential se…

Real-space visualization of orbital-selective superconductivity in FeSe
Sang Yong Song, Gábor B. Halász, Jiaqiang Yan +2
We investigate the orbitally resolved superconducting properties of bulk FeSe using scanning tunneling microscopy (STM). We find that the spectral weights of both the large a…
