Query: Unveiling the optical emission channels of monolayer semiconductors
  coupled to silicon nanoantennas   Monolayers (MLs) of transition metal dichalcogenides (TMDs) such as WSe2 and
MoSe2 can be placed by dry stamping directly on broadband dielectric
resonators, which have the ability to enhance the spontaneous emission rate and
brightness of solid-state emitters at room temperature. We show strongly
enhanced emission and directivity modifications in room temperature
photoluminescence mapping experiments. By varying TMD material (WSe2 versus
MoSe2) transferred on silicon nanoresonators with various designs (planarized
versus non-planarized), we experimentally separate the different physical
mechanisms that govern the global light emission enhancement. For WSe2 and
MoSe2 we address the effects of Mie Resonances and strain in the monolayer. For
WSe2 an important additional contribution comes from out-of-plane exciton
dipoles. This paves the way for more targeted designs of TMD-Si nanoresonator
structures for room temperature applications.
