where E(X-MoTe 2 ) is the energy of the doped layer (see Figure for the model structure), E(vacancy) is the energy of monolayer with vacancy (see Figure ) and E(X) is the energy of the single isolated dopant atom in vacuum. Generally, in studies discussing doped-TMD based sensors, shown in Table , there are only a few investigated dopants, with many scientific articles exclusively focusing on only one.
