Resistivity vs Temperature

Caption

The results show that resistivity begins to decrease sharply at temperatures below 40 K regardless of the thickness of the FeSe layer. This means that two-dimensional superconductivity in FeSe/STO occurs at the interface rather than across all FeSe layers. ρ2D: two-dimensional resistivity, UC: unit-cell thickness.
