Extension of Friedel's law to Vortex Beam Diffraction
Roeland Juchtmans, Giulio Guzzinati, Jo Verbeeck
Friedel's law states that the modulus of the Fourier transform of real functions is centrosymmetric, while the phase is antisymmetric. As a consequence of this, elastic scattering…
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…
Shaping electron beams for the generation of innovative measurements in the (S)TEM
Jo Verbeeck, Giulio Guzzinati, Laura Clark +6
In TEM, a typical goal consists of making a small electron probe in the sample plane in order to obtain high spatial resolution in scanning transmission electron microscopy. In ord…
