Abstract
The monolayer MoS2 offer wide band gap and has great potential in energy storage, sensor, photonics. In this paper, we design and simulate a perfect absorber based on the local surface plasmon resonance and the coupling properties between the Ag pattern and the monolayer MoS2. The absorption value is almost 100% at peak, and the bandwidth of the absorption greater than 90% can reach 20THz. It is also polarization independent due to the fourfold rotational structural symmetry. The absorption value still remains over 90% when the incident angle increases to 60 degrees. The absorber has a great potential in many applications such as photodetectors, solar cell, sensors.
