A characteristic feature of the electronic structure of iron-based superconductors is the shift of experimental electronic bands in comparison to the results of calculations. This shift is most likely a result of electron–electron interaction. In some recent papers, a hypothesis that the shift, together with interaction magnitude, should decrease with temperature is proposed, and some experimental evidences are presented to support it. We investigate in details the evolution of electronic band structure of FeSe in temperature range from 20 to 250 K. We conclude that the shift of $d_{xy}$-band in the centre of the Brillouin’s zone results in the opposite effect—binding energy of $d_{xy}$-electrons increases with increasing of temperature.

Key words: angle resolved photoemission spectroscopy (ARPES), electronic structure of FeSe, iron-based superconductors, curvature method.
