Title: Iron-based Superconductors

Abstract：

The iron based superconductors are expected to have strong potential in electricity transport, high magnetic field and sensitive magnetic detection. One of the on-going frontier studies on iron based superconductors is about the pairing mechanism. The Fermi surfaces in different systems are extremely distinct: some have both electron and hole pockets, but others have only the electron pockets. Therefore there is no consensus yet about the pairing gap structure and pairing mechanism. We have conducted extensive STM/STS studies on many different iron based superconductors and try to explore a unified understanding of the pairing mechanism in all iron based superconductors.
