正如CuO平面是高Tc铜酸盐超导体的基本组成部分一样，FeAs层是新发现的FeAs基超导磷属元素化物的基本结构1。然而，与铜酸盐中的刚性CuO平面不同，在FeAs层内用Co或Ni部分取代Fe或用P部分取代As可以有效地诱导超导性234。从这个意义上说，在二元FeSex（Tc = 8K）中发现超导电性是很有意义的，因为它只包含与FeAs层具有相同结构的超导FeSe层，并且Se的缺乏可能导致超导电性。
Just as CuO-plane is the basic building block of high-Tc cuprate superconductors, the FeAs-layer is the basic structure of the newly discovered FeAs-based superconducting pnictides 1. However, unlike the rigid CuO-plane in cuprates, partial substitution of Fe by Co or Ni, or As by P within the FeAs-layer can effectively induce superconductivity 234. In this sense, the discovery of superconductivity in binary FeSex (Tc∼8 K) is of great interests, since it only contains the superconducting FeSe-layer which has identical structure as FeAs-layer, and the Se deficiency may cause the superconductivity 5.
