Orbital angular momentum in electron diffraction and its use to determine chiral crystal symmetries
Roeland Juchtmans, Jo Verbeeck
In this work we present an alternative way to look at electron diffraction in a transmission electron microscope. In stead of writing the scattering amplitude in Fourier space as a…

Using electron vortex beams to determine chirality of crystals in transmission electron microscopy
Roeland Juchtmans, Armand Béché, Artem Abakumov +2
We investigate electron vortex beams elastically scattered on chiral crystals. After deriving a general expression for the scattering amplitude of a vortex electron, we study its d…
