Beam self-focusing in the near field emission scanning electron microscopy

ORAL

Abstract

Recent experiment on the near field emission scanning electron microscopy shows an unexpectedly high lateral and vertical resolution. We show that these effects can be explained by the beams self-focusing. We derive the equations for the beam propagation and solve them numerically. Our results are in a very good agreement with the experiment.
