Common (π,π) Band Folding and Surface Reconstruction in FeAs-Based Superconductors

High resolution angle-resolved photoemission spectroscopy (ARPES) measurements are carried out on CaKFe 4 As 4 , KCa 2 Fe 4 As 4 F 2 and (Ba 0.6 K 0.4 )Fe 2 As 2 superconductors. Clear evidence of band folding between the Brillouin zone center and corners with a ( π , π ) wave vector has been found...
