Electron emission near nanocylinders of Al

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 the surface of a nanostructured (cylindrically shaped) solid - can influence the probability of surface plasmon excitations and consequently the energy loss of the emerging electrons. The method described here is useful for understanding the electron spectra excited from these different nanostructures.
