文摘

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.
