Paper Abstract

We develop a theory for surface-assisted plasmon decay in metal nanostructures of arbitrary shape. We derive the rate of electron surface scattering, which facilitates plasmon decay in small nanostructures, that is determined by local field polarization relative to metal-dielectric interface and is highly sensitive to the system geometry. We show that the surface scattering can be incorporated into metal dielectric function on par with phonon and impurity scattering. We illustrate our model by providing analytical results for surface scattering rate in some common shape nanostructures. Our results can be used for calculations of hot carrier generation rates in photovoltaics and photochemistry applications.
