We have performed in-situ angle-resolved photoemission spectroscopy measurements of cesium(Cs)-deposited FeSe thin films on SrTiO3. We found that Cs deposition enables heavily electron doping into the FeSe layer. In properly doped films, we also revealed the occurrence of superconductivity accompanied by the suppression of electronic nematicity. The present result demonstrates that Cs deposition is an effective way to realize and enhance superconductivity in FeSe.
