Residual neural-field ptychography for dose-efficient electron, X-ray, and optical nanoscopy
Qianhao Zhao, Zhixuan Hong, Ruihai Wang +7
Ptychography spans from sub-angstrom to meter scales yet suffers from convergence instability and excessive data redundancy. Here we introduce self-correcting residual neural field…
Towards reliable electrical measurements of superconducting devices inside a transmission electron microscope
Joachim Dahl Thomsen, Michael I. Faley, Joseph Vimal Vas +6
Correlating structure with electronic functionality is central to the engineering of quantum materials and devices whose properties depend sensitively on disorder. Transmission ele…
Electrostatic interference control of a high-energy coherent electron beam using a three-element Boersch phase shifter
Pooja Thakkar, Vitaliy A. Guzenko, Peng-Han Lu +3
In contrast to static holographic phase shifters, which are restricted to specific electron beam energies and microscope settings, Boersch phase shifters are promising for creating…
Magnetic Phase Imaging using Lorentz Near-field Electron Ptychography
Shengbo You, Peng-Han Lu, András Kovács +4
Over the past few years, the combination of diffuser and near-field electron ptychography has drawn more attention by its ability to recover large field of view with few diffractio…
Generation of electron vortex beams with over 1000 orbital angular momentum quanta using a tuneable electrostatic spiral phase plate
A. H. Tavabi, P. Rosi, A. Roncaglia +9
We report the use of an electrostatic MEMS-based device to produce high quality electron vortex beams with more than 1000 quanta of orbital angular momentum (OAM). Diffraction and…
Experimental demonstration of an electrostatic orbital angular momentum sorter for electrons
Amir H. Tavabi, Paolo Rosi, Giulio Pozzi +9
We report the first experimental demonstration of an electrostatic electron orbital angular momentum (OAM) sorter, which can be used to analyze the OAM states of electrons in a tra…
Realization of electron vortices with large orbital angular momentum using miniature holograms fabricated by electron beam lithography
E. Mafakheri, A. H. Tavabi, P. -H. Lu +9
Free electron beams that carry high values of orbital angular momentum (OAM) possess large magnetic moments along the propagation direction. This makes them an ideal probe for meas…
