Shifting of surface plasmon resonance due to electromagnetic coupling between graphene and Au nanoparticles

Jing Niu, +5 more
- 23 Aug 2012 - 
TL;DR: Shifting of the surface plasmon resonance wavelength induced by the variation of the thickness of insulating spacer between single layer graphene and Au nanoparticles is studied and the result agrees qualitatively well with the plAsmon ruler equation.
Journal ArticleDOI
