Abstract

We present the perfect light absorption of monolayer molybdenum disulfide (MoS₂) in a dielectric multilayer system with two different Bragg mirrors. The results show that the strong absorption of visible light in monolayer MoS₂ is attributed to the formation of optical Tamm states (OTSs) between two Bragg mirrors. The MoS₂ absorption spectrum is dependent on the layer thickness of Bragg mirrors, incident angle of light, and the period numbers of Bragg mirrors. Especially, the nearly perfect light absorption (99.4%) of monolayer MoS₂ can be achieved by choosing proper period numbers, which is well analyzed by the temporal coupled-mode theory.
