Popis: Surface plasmon polaritons (SPPs) enable the light to confine to sub-wavelength space. Metallic nanostructure is often used for plasmonic device since plasmon resonance band is generally formed at visible regime. SPPs lead to several orders enhancement of incident light intensity at the metallic nanosurface. While this remarkable effect has been studied for useful application (e.g. SERS, TERS photoluminescence, etc.), it was found plasmon generated highly energetic carriers through Landau damping, referred as hot electrons and holes. The hot carrier induces chemical transformation of molecules at the plasmonic nanosurface. The fact chemically inert molecules reacted by hot carrier has been reported in the recent [1].
