The electronic structure of Co-substituted $\text{Fe}\text{Se}$ superconductor probed by soft X-ray spectroscopy and density functional theory

I. Perez, J. A. McLeod, R. J. Green +3

We study the crystalline and electronic properties of the ${\text{Fe}}_{1-x}{\text{Co}}_x\text{Se}$ system ($x=0$, 0.25, 0.5, 0.75, and 1.0) using X-ray diffraction, X-ray spectr…
