Abstract

The first observations of surface-enhanced resonance Raman scattering (SERRS) from tris(bipyridine)ruthenium(II), Ru(bpy)32+, at monolayer (or less) coverage on n-GaAs(100) semiconductor (SC) electrodes modified by the electrodeposition of ca. 100 monolayers of Ag metal are reported. In addition to the SERRS studies, the photoelectrochemical and surface microstructural properties of Ag/GaAs/Ru(bpy)32+ electrodes were studied by cyclic voltammetry (CV) and scanning electron microscopy (SEM).
