Plasmonics Enhanced Average Broadband Absorption of Monolayer MoS2

Article

Abstract

We have studied characterization of micromechanical cleavage monolayer molybdenum disulfide (MoS2) deposited on SiO2/Si and glass substrates. Spherical gold (Au) nanoparticles were anchored on top of monolayer MoS2 film. Direct reflection spectra were measured, which infers significant improvement of total average absorption of monolayer MoS2 in Vis-NIR range of 400–800 nm by the plasmonic absorption of Au nanoparticles. Nearly 8 % average absorption was obtained in monolayer MoS2 sample, which was increased up to 41 % by plasmonic Au nanoparticles deposited on monolayer MoS2 film. Numerical results are also provided to describe the phenomena. This study will further add the possibilities of using layered materials in the area of solar absorption-based nano-optoelectronic devices.
