Abstract

By the use of density functional calculations it is shown that the edges of a two-dimensional slab of insulating ${MoS}_{2}$ exhibit several metallic states. These edge states can be viewed as one-dimensional conducting wires, and we show that they can be observed directly using scanning tunneling microscopy for single-layer ${MoS}_{2}$ nanoparticles grown on a support.
