Electron energy loss for isolated cylinders

The interaction of STEM electrons with cylindrical surfaces is investigated within the framework of the self-energy formalism. The energy loss is studied as a function of the impact parameter and for the case of broad beam geometries. An expression for the effective inverse longitudinal dielectric f...

Description
Summary:The interaction of STEM electrons with cylindrical surfaces is investigated within the framework of the self-energy formalism. The energy loss is studied as a function of the impact parameter and for the case of broad beam geometries. An expression for the effective inverse longitudinal dielectric function of isolated cylinders is derived, and applications of this theory are reviewed.
