The contact properties of Ni, Au, and Mo with MoS<sub>2</sub> are simulated by the first-principles method. The interface dipole caused by the interface charge redistribution changes the work function difference at the metal-MoS<sub>2</sub> interface, so the interface charge redistribution is one of the important factors for correctly evaluating the contact properties. Due to the metal-induced gap states (MIGS) at metal-monolayer (ML) MoS<sub>2</sub> interfaces, the Fermi level is strongly pinned to fixed energy, and the Schottky barrier height (SBH) cannot be regulated efficiently by the metal work function. Although the work function of Au is bigger than Ni, the Fermi level of Au is pinned at a higher position. In the meantime, the bandgap of MoS<sub>2</sub> narrows and metallization occurs due to the larger MIGS. In the Mo-MoS<sub>2</sub> interface, the Fermi level is pinned near the conduction band minimum of MoS<sub>2</sub>. The contact resistances (R<sub>c</sub>) of the three structures are tested by the Circular Transfer Length Method (CTLM), which is consistent with the prediction of the simulation.
