TLDR
A nano-plasmonic study of vdW heterostructures that were produced by depositing ordered molecular layers of pentacene on top of graphene finds that surface plasmons formed due to the collective oscillations of Dirac fermions in graphene are highly sensitive to the adjacentpentacene layers.Abstract:
van der Waals (vdW) heterostructures, which are produced by the precise assemblies of varieties of two-dimensional (2D) materials, have demonstrated many novel properties and functionalities. Here ...read more
