Supercell studies of the Fermi surface changes in the electron-doped superconductor LaFeAsO${}_{1-x}$F${}_x$

P. Larson, S. Satpathy

We study the changes in the Fermi surface with electron doping in the LaFeAsO${}_{1-x}$F${}_x$ superconductors with density-functional supercell calculations using the linearized augme…
