We experimentally study the surface roughness and the lateral friction forcein single-layer MoS2 crystals deposited on different substrates: SiO2, mica andhexagonal boron nitride (h-BN). Roughness and sliding friction measurements areperformed by atomic force microscopy (AFM). We find a strong dependence of theMoS2 roughness on the underlying substrate material, being h-BN the substratewhich better preserves the flatness of the MoS2 crystal. The lateral frictionalso lowers as the roughness decreases, and attains its lowest value for MoS2flakes on h-BN substrates. However, it is still higher than for the surface ofa bulk MoS2 crystal, which we attribute to the deformation of the flake due tocompeting tip-to-flake and flake-to-substrate interactions.
