Energy loss probability of STEM electrons in cylindrical surfaces

Abstract

In the frame of the self-energy formalism, the interaction of STEM electrons with a cylindrical surface is studied. The surface modes of cylindrical interfaces so obtained are proven to fulfil certain sum rules. A general expression for the energy loss probability valid for any beam direction nonparallel to the cylinder axis is presented. In all the cases the so-called begrenzung effect is found.The authors gratefully acknowledge Guipuzkoako Font Aldundia for help and support.Peer reviewe
