Abstract

The electronic structure of the iron chalcogenide superconductor FeSe_1\ensuremath-x was investigated by high-resolution angle-resolved photoemission spectroscopy (ARPES). The results were compared to DFT calculations showing some significant differences between the experimental electronic structure of FeSe_1\ensuremath-x, DFT calculations, and existing data on FeSe_xTe_1\ensuremath-x. The bands undergo a pronounced orbital-dependent renormalization, different from what was observed for FeSe_xTe_1\ensuremath-x and any other pnictides.
