V-shaped active plasmonic -polymers

We report the design and fabrication of V-shaped plasmonic meta -polymers on a glass substrate or silicon wafer using a surface functionalization approach. The efficacy of the assembly method is examined by analyzing the surface enhanced Raman scattering by an individual V-shaped antenna experimentally and using computational simulations to determine the polarization dependence of local electromagnetic field enhancement. A facile, cheap, and scalable method for the fabrication of V shaped plasmonic meta -polymers on a glass substrate/silicon wafer has been reported. This V shaped antenna shows unique polarization and electric field signatures and enhances molecular signatures in the near field.
