Transport of Intensity Phase Retrieval of Arbitrary Wave Fields Including Vortices
Axel Lubk, Giulio Guzzinati, Felix Börrnert +1
The phase problem can be considered as one of the cornerstones of quantum mechanics intimately connected to the detection process and the uncertainty relation. The latter impose fu…
Topological analysis of paraxially scattered electron vortex beams
Axel Lubk, Laura Clark, Giulio Guzzinati +1
We investigate topological aspects of sub-nm electron vortex beams upon elastic propagation through atomic scattering potentials. Two main aspects can be distinguished: (i) Signifi…
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…
Measuring the Orbital Angular Momentum of Electron Beams
Giulio Guzzinati, Laura Clark, Armand Béché +1
The recent demonstration of electron vortex beams has opened up the new possibility of studying orbital angular momentum (OAM) in the interaction between electron beams and matter.…
