Overcoming contrast reversals in focused probe ptychography of thick materials: an optimal pipeline for efficiently determining local atomic structure in materials science
C. Gao, C. Hofer, D. Jannis +3
Ptychography provides highly efficient imaging in scanning transmission electron microscopy (STEM), but questions have remained over its applicability to strongly scattering sample…
Can a Programmable Phase Plate Serve as an Aberration Corrector in the Transmission Electron Microscope (TEM)?
Francisco Vega Ibáñez, Armand Béché, Johan Verbeeck
Current progress in programmable electrostatic phase plates raises questions about their usefulness for specific applications. Here, we explore different designs for such phase pla…
Symmetry-constrained electron vortex propagation
L. Clark, G. Guzzinati, A. Béché +2
Electron vortex beams hold great promise for development in transmission electron microscopy, but have yet to be widely adopted. This is partly due to the complex set of interactio…
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…
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…
Exploiting lens aberrations to create electron vortex beams
L. Clark, A. Béché, G. Guzzinati +4
A model for a new electron vortex beam production method is proposed and experimentally demonstrated. The technique calls on the controlled manipulation of the degrees of freedom o…
Magnetic monopole field exposed by electrons
A. Béché, R. Van Boxem, G. Van Tendeloo +1
Magnetic monopoles have provided a rich field of study, leading to a wide area of research in particle physics, solid state physics, ultra-cold gases, superconductors, cosmology, a…
