Probing the local nature of excitons and plasmons in few-layer MoS2

Probing excitons and plasmons at the nanoscale This paper outlines a template protocol to map the local nature of electronic excitations were they happen, at the nanoscale. An unprecedented combination of energy and spatial resolution (using monochromated low-loss scanning-transmission-electron-micr...
