摘要

Both unconventional high-temperature superconductors,cuprate-and iron-based superconductors, carry quasi-two-dimensional (Q2D) electronic structures that are attributed to the 3d electrons of the transition metal elements, Cu or Fe.The reduced dimensionality and the 3d electrons are believed to be the two main factors to cause the strong electron-electron correlation in these materials.How the superconductivity and many intriguing phenomena are developed in these strongly correlated systems has been a central research frontier in the field of condensed matter physics in the past three decades.
