Author(s): Tuomas P. Rossi, Kirsten T. Winther, Karsten W. Jacobsen, Risto M. Nieminen, Martti J. Puska, and Kristian S. Thygesen The electronic edge states of MoS 2 nanoparticles are important for the catalytic activity of the particles and could also have potential for photocatalysis. Here, the authors explore computationally optical properties of MoS 2 monolayer nanoflakes. These nanostructures show a rich size-dependent optical response below the absorption onset of the infinite monolayer. The authors present a detailed analysis of the emerging optical absorption resonances revealing their edge-state origins. In particular, metallic edge states support localized edge plasmons, and overall, resonances are sensitive to changes in the edge-atom configuration. [Phys. Rev.
