... a lamellar structure, in which each molybdenum atom is sandwiched between the two sulfur atoms in the trigonal prismatic geometry. The molecular lamellae of MoS 2 are held together by the weak van der Waals interactions, which facilitate the shearing under the sliding stress and reduce the friction [ 35...
