Abstract : 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 symmetry in their crystallographic structure [2]. Many promising recent efforts in control of excitonic transitions in these materials have been devoted to study of their coupling with plasmonic nanoresonators. Plasmonic nanoresonators are known for their ability to control and modify the optical response of materials in their proximity [3]. These findings have motivated the study of emergent phenomena associated with the plasmon exciton interaction in these hybrid systems [4-5], which include enhancement [6] and quenching of the TMDs photoluminescence [7].
