摘要
The electronic structure of the Fe-based superconductors is discussed, mainly from the point of view of first principles calculations in relation to experimental data. Comparisons and contrasts with cuprates are made. The problem of reconciling experiments indicating an s symmetry gap with experiments indicating line nodes is discussed and a possible resolution is given. (C) 2009 Elsevier B.V. All rights reserved.
