Enhanced Light Absorption and Efficient Carrier Collection in MoS₂ Monolayers on Au Nanopillars

Nanomaterials, 2022
We fabricated hybrid nanostructures consisting of MoS2 monolayers and Au nanopillar (Au-NP) arrays. The surface morphology and Raman spectra showed that the MoS2 flakes transferred onto the Au-NPs were very flat and nonstrained.
