Transition Metal Dichalcogenide (TMD) materials have increasingly gained attention, due to their unique optical, spintronic, and electronic properties [1]. These properties at the monolayer limit are by part a result of the ultimate confinement imposed on their excitonic transitions that originate a direct band-gap and a lack of inversion...

In this work we investigate the interaction between plasmonic and excitonic resonances in hybrid MoSe2@Au nanostructures. The latter were fabricated by combining chemical vapor deposition of MoSe2 atomic layers, Au disk processing by nanosphere lithography and a soft lift-off/transfer technique. The samples were characterized by scanning...

We report on the surface enhanced resonant Raman scattering (SERRS) in hybridMoSe2@Au plasmonic-excitonic nanostructures, focusing on the situation where the localizedsurface plasmon resonance of Au nanodisks is finely tuned to the exciton absorption ofmonolayer MoSe2. Using a resonant excitation, we investigate the SERRS in MoSe2@Au andthe...

Combining localized surface plasmons and confined excitons in hybrid metallic/semiconductor nanostructures is a promising route toward the manipulation of the light-matter interaction at the nanoscale and the generation of novel technological applications. In this context, we investigate the interference between plasmonic and excitonic...

We report on photo-current generation in freestanding monolayered gold nanoparticle membranes excited by using a laser. The absence of a substrate leads to a 50% increase of the photocurrent at plasmon resonance. This current is attributed to a combination of trap state dynamics and bolometric effects in a nanocomposite medium yielding a...
