| الوصف: | The surface plasmon dispersion of Ag(111) tuned by adsorption of F4-TCNQ molecules has been investigated using high resolution electron energy loss spectroscopy. For the pristine Ag(111) film, the surface plasmon energy shows a positive quadratic dispersion. After adsorption of F4-TCNQ, the plasmon energy of Ag decreases significantly and the dispersion switches sign at small q||. The deviation systematically increases with the coverage of F4-TCNQ. These behaviors are explained by charge transfer between the Ag substrate and the molecular gas layer. |
