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…
Epitaxial growth of complex oxides on silicon by enhanced surface diffusion in large area pulsed laser deposition
Rik Groenen, Zhaoliang Liao, Nicolas Gauquelin +11
Homogeneous highly epitaxial LaSrMnO3 (LSMO) thin films have been grown on Yttria-stabilized-Zirconia (YsZ) / CeO2 buffer layers on technological relevant 4" silicon wafers using a…
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…
Atomic scale electron vortices for nanoresearch
J. Verbeeck, P. Schattschneider, S. Lazar +4
Electron vortex beams were only recently discovered and their potential as a probe for magnetism in materials was shown. Here we demonstrate a new method to produce electron vortex…
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…
