Spectroscopic coincidence experiments in transmission electron microscopy
Daen Jannis, Knut Müller-Caspary, Armand Béché +2
We demonstrate the feasibility of coincidence measurements in a conventional transmission electron microscope, revealing the temporal correlation between electron energy loss spect…
Electron Bessel beam diffraction for precise and accurate nanoscale strain mapping
Giulio Guzzinati, Wannes Ghielens, Christoph Mahr +4
Strain has a strong effect on the properties of materials and the performance of electronic devices. Their ever shrinking size translates into a constant demand for accurate and pr…
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…
A new way of producing electron vortex probes for STEM
J. Verbeeck H. Tian A. Béché
A spiral holographic aperture is used in the condensor plane of a scanning transmission electron microscope to produce a focussed electron vortex probe carrying a topological charg…
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…
