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…
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…
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…
Convergent beam electron-diffraction investigation of lattice mismatch and static disorder in GaAs/GaAs1-xNx intercalated GaAs/GaAs1-xNx:H heterostructures
Stefano Frabboni, Vincenzo Grillo, Gian Carlo Gazzadi +8
Hydrogen incorporation in diluted nitride semiconductors dramatically modifies the electronic and structural properties of the crystal through the creation of nitrogen-hydrogen com…
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…
