The lubrication properties of MoS 2 have been described in terms of electronic interactions between MoS 2 sheets calculated through slab periodic density functional calculations. This approach is supported by experimental works on the ultrahigh vacuum friction of MoS 2 coatings of thicknesses in the micrometer range (Phys. Rev. 48 (14) (1993) 10583), and in boundary lubrication...
