Factors limiting quantitative phase retrieval in atomic-resolution differential phase contrast scanning transmission electron microscopy using a segmented detector
T. Mawson, D. J. Taplin, H. G. Brown +10
Quantitative differential phase contrast imaging of materials in atomic-resolution scanning transmission electron microscopy using segmented detectors is limited by various factors…
Theory and applications of free-electron vortex states
K. Y. Bliokh, I. P. Ivanov, G. Guzzinati +8
Both classical and quantum waves can form vortices: with helical phase fronts and azimuthal current densities. These features determine the intrinsic orbital angular momentum carri…
Investigation into spiral phase plate contrast in optical and electron microscopy
Roeland Juchtmans, Laura Clark, Axel Lubk +1
The use of phase plates in the back focal plane of a microscope is a well established technique in optical microscopy to increase the contrast of weakly interacting samples and is…
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…
Prospects for versatile phase manipulation in the TEM: beyond aberration correction
Giulio Guzzinati, Laura Clark, Armand Béché +4
In this paper we explore the desirability of a transmission electron microscope in which the phase of the electron wave can be freely controlled. We discuss different existing meth…
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…
