Porosity effect on surface plasmon resonance from metallic sculptured thin films
Porosity effect on surface plasmon resonance from metallic sculptured thin films
When a sculptured thin film (STF), made of a metal and ≤ 50 nm thick, is used in lieu of a dense layer of metal in the Kretschmann configuration, experimental data for a STF comprising parallel tilted nanowires shows that a surface plasmon resonance (SPR) can still be excited. As …
