Surface plasmons resonance is an unique optical property of metallic nanostructures.The recent extensive research on surface plasmons in metallic nanostructures has merged into a new subject,named plasmonics.By using light trapping through the resonant scattering and the near field enhancement in arrays of metal nanoparticles,or by coupling light into surface plasmon polaritons modes that propagate in the plane of the semiconductor layer,the enhancement of light absorption and the improvement of conversion ...
