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…
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…
Quantitative measurement of orbital angular momentum in electron microscopy
L. Clark, A. Béché, G. Guzzinati +1
Electron vortex beams have been predicted to enable atomic scale magnetic information measurement, via transfer of orbital angular momentum. Research so far has focussed on develop…
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.…
