Popis:	The origin of superconductivity in FeSe monolayer on SrTiO$_3$ belongs to one of the unresolved mysteries in condensed-matter physics. Here by investigation of the temperature evolution of the dynamic charge response of FeSe/SrTiO$_3$ we demonstrate that the response of the monolayer itself is nearly temperature independent. This indicates a constant Fermi surface over a wide range of temperature, in stark contrast to that of the bulk FeSe and other Fe-based superconductors. Our results, which manifest the peculiarity of the electronic structure of the FeSe monolayer, may help for a microscopic understanding of the superconductivity in Fe-chalcogenide monolayers on oxide surfaces in general. Comment: 7 Pages, 3 Figures
