Abstract

Electron energy-loss spectroscopy (EELS) is suggested as a possible probe for the longitudinal plasmon sub-bands in metallic superlattices. An outline of the theory leading to the dispersion relation and the scattering cross section is given. The treatment applies the dispersive hydrodynamic jellium model for the field quantisation of the superlattice longitudinal plasmons and standard scattering theory for the derivation of the cross section. The feasibility of the suggested EELS experiment is examined by application of the theory to a typical metallic superlattice.
