Abstract
Localized emitters in atomically thin 2D materials and lateral heterostructures are of interest for flexible optoelectronic and nanoscale quantum applications. We investigate near-field photoluminescence (PL) and Raman signals of local heterogeneities such as nanobubbles, lateral heterostructures and alloys in monolayer and few-layer transition metal dichalcogenides coupled via polariton-like surface waves and plasmon-enhanced hot electrons. We investigate various emitter coupling schemes and near-field enhancement mechanisms and demonstrate near-field imaging of exciton funnels, revealing a strong synergistic enhancement of the PL signals due to the plasmonic antenna tip, hot electron injection, and exciton funnelling. This opens new avenues in exploration of novel nanophotonic coupling schemes.
