Constraining the Superconducting Gap of Monolayer FeSe/SrTiO${}_3$ via Statistical Analysis and Tip-Height-Dependent Tunneling Spectroscopy

Dongwon Shin, Xiyou Peng, Kaleb McClure +6

Monolayer FeSe grown on SrTiO${}_3$ (001) exemplifies interface-enhanced superconductivity, exhibiting a transition temperature nearly ten times that of bulk FeSe. Yet, its tunneling…
