A full gap above the Fermi level: the charge density wave of monolayer VS2

A full gap above the Fermi level: the charge density wave of monolayer VS2

A charge density wave (CDW) normally creates a gap at the Fermi level, inducing a metal-insulator transition. Here, the authors report that a CDW gap resides in the unoccupied states but induces a topological metal-metal transition at the Fermi level in monolayer VS2.
