Various ordered electronic phases, such as nematicity and spin density waves, have also been observed accompanying high-$T_{\\rm{c}}$ superconductivity. Investigation on the evolution of the electronic structure with $T_{\\rm{c}}$ is essential to understanding electronic behavior and high-$T_{\\rm{c}}$ superconductivity in FeSe and its derived superconductors.
