Enhanced superconductivity accompanying a Lifshitz transition in electron-doped FeSe monolayer

The origin of superconductivity enhancement in FeSe monolayer grown on SrTiO3 compared to bulk FeSe is still a debated issue. Here, Shi et al. report a further 15 K jump of Tc accompanying a second Lifshitz transition triggered by electron doping in FeSe/SrTiO3monolayer films.
