Abstract

We investigate the dynamical dielectric function of a monolayer of molybdenum disulfide within the random phase approximation. While in graphene damping of plasmons is caused by interband transitions, due to the large direct band gap in monolayer MoS2 collective charge excitations enter the intraband electron hole continuum similarly to the situation in two-dimensional electron and hole gases. ...
