Abstract

In this work we investigate in detail the effects due to the interaction between an electron and a stationary positive ion (or atomic hole) in the neighbourhood of a nanostructured surface. In particular, we study how a positive charge, located near to the surface of a nanostructured (cylindrically shaped) body, can influence the probability of the surface plasmon excitations and consequently the energy loss of the emerging electron. We deal with simple nanostructured systems of Al, having a strong plasmon peak in its electron energy loss spectra. The method described here is useful for understanding the electron spectra excited from these nanostructures (different from those of the same bulk material).
