The iron chalcogenide superconductor FeSe has attracted much attention because the monolayer film on SrTiO₃ shows a large enhancement of superconductivity due to interface effects. However, superconducting fluctuation is considered to dominate in a temperature range of more than 20 K due to its low dimensionality. In this study, we investigated superconducting fluctuation in ultrathin FeSe/STO₃ using the Nernst effect measurement.
