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…
