Exciton-dominated Dielectric Function of Atomically Thin MoS(2) Films

We systematically measure the dielectric function of atomically thin MoS(2) films with different layer numbers and demonstrate that excitonic effects play a dominant role in the dielectric function when the films are less than 5–7 layers thick. The dielectric function shows an anomalous dependence o...
