The dielectric functions of gold nanoparticle (Au NP) self-assembled on Si substrates without and with a SiO2 layer (3, 10 and 30 nm in thickness) have been examined. For Au NP on Si substrate without a SiO2 layer, a splitting in surface plasmon resonance (SPR) band in the imaginary part of the diel...
