Electronic structure and hybridization of CaS by means of X-ray absorption spectroscopy at Ca and S K-edges

A discussion on the electronic structure and particular hybridization of CaS via ab initio calculations of X-ray absorption spectra is presented.

Strikingly dissimilar effect of Mn and Zn dopants imposed on local structural distortion of Ba_0.5K_0.5Fe₂As₂ superconductor

The contrasting impurity effects of Mn and Zn dopants on the critical temperature of optimally doped Ba_0.5K_0.5Fe₂As₂ superconductors have been investigated by Fe and As K-edge X-ray absorption fine-structure spectroscopy.
