NbSe2, a true 2-D superconductor

An international team led by Miguel M. Ugeda and Michael F. Crommie has demonstrated the coexistence of superconductivity and charge density wave order in a single layer of NbSe2, a model transition metal dichalcogenide metal. The demonstration that a single layer of NbSe2 is a true 2-D superconductor is a breakthrough in the field of 2-D materials. This work has been recently reported in Nature Physics.
