Creation of electron vortex beams using the holographic reconstruction method in a scanning electron microscope
Řiháček, Tomáš ; Horák, M. ; Schachinger, T. ; Matějka, Milan ; Mika, Filip ; Müllerová, Ilona
Electron vortex beams (EVB) were theoretically predicted in 2007 and first experimentally\ncreated in 2010. Although they attracted attention of many researchers, their\ninvestigation takes place almost solely in connection with transmission electron microscopes (TEM). On the other hand, although scanning electron microscopes (SEM) may provide some advantages for EVB applications, only little attention has been dedicated to them. Therefore, the aim of this work is to create electron vortices in SEM at energies of several keV.
