Current literature concerning modification of tungsten TMD monolayers with metals typically investigates the effect of either doping, or adsorption of metals. Studies concerning monolayer doping, generally where metal atoms substitute a chalcogen atom in the monolayer, investigate the dopant's effects on electronic and magnetic properties (Mn, Fe, Co, and Ni doped WS 2 ) , optical properties (V on WSe 2 ) , and gas sensing (Cu, Co, Rh, Ir doped WS 2 and Ni doped WTe 2 ) [57 . There are also studies concerning doping at the metal rather than the chalcogen site in TMD monolayers (Re, Au, or W doping MoS 2 ) , however these studies are less widespread.
