We report long-range ferromagnetic ordering in a vanadium-doped monolayer WSe2 semiconductor using spin-polarized density functional calculations. We found that the vanadium dopant is located in the fully occupied state inside the valence band, inherent from spin–orbit coupling, leading to the presence of free holes in the valence band. As a consequence, the spin-polarized hole carriers are delocalized not only in the vanadium site but also persistently in the tungsten sites distant from vanadium to facilitate the long-range ferromagnetic ordering in the vanadium-doped monolayer WSe2. Our findings of this study pave the way for the future exploration of carrier-mediated room-temperature two-dimensional ferromagnetic semiconductors via magnetic dopants.
