Evidence of electronic polarization of the As ion in the superconducting phase of F-doped LaFeAsO

Evidence of electronic polarization of the As ion in the superconducting phase of F-doped LaFeAsO

Understanding the nature of superconductivity in iron-based compounds is essential in the development of new strategies to increase Tc. Using a charge density analysis based on synchrotron radiation X-ray powder diffraction data, we found that the charge carriers only accumulated in the iron layer o...
