摘要：
The assembly of metal/semiconductor/molecule was fabricated with gold nanoparticles, ZnO, and 4-aminothiophenol (PATP) molecules through the layer-by-layer self-assembly method. Raman spectra of PATP adsorbed on Au/ZnO were considerably enhanced relative to those observed on Au particles alone. By examining the relative enhancement of the nontotally symmetric (b(2)) modes, this effect is shown to arise from a charge transfer (CT) contribution from the metal to molecule.
