Metal-molecule charge transfer through Fermi level equilibration in plasmonic systems

Despite recent promising advances in plasmonic chemistry and chemical reactions on the surface of metal nanostructures, it is still challenging to control the adsorption of molecules and the charge transfer processes occurring at the metal–molecule interface [1] . This study describes a simple method to control metal-molecule charge transfer processes by tuning the surface potential and, consequently, the Fermi energy of silver nanoparticles (AgNPs) in-situ.
