| 英文摘要 | The standard hydrodynamic drude model with hard-wall boundary conditions can give accurate quantitative predictions for the optical response of noble-metal nanoparticles. however, it is less accurate for other metallic nanosystems, where surface effects due to electron density spill-out in free space cannot be neglected. here we address the fundamental question whether the description of surface effects in plasmonics necessarily requires a fully quantum-mechanical ab initio approach. we present a self-consistent hydrodynamic model (sc-hdm), where both the ground state and the excited state properties of an inhomogeneous electron gas can be determined. with this method we are able to explain the size-dependent surface resonance shifts of na and ag nanowires and nanospheres. the results we obtain are in good agreement with experiments and more advanced quantum methods. the sc-hdm gives accurate results with modest computational effort, and can be applied to arbitrary nanoplasmonic systems of much larger sizes than accessible with ab initio methods. |
