Near-real-time diagnosis of electron optical phase aberrations in scanning transmission electron microscopy using an artificial neural network
Giovanni Bertoni, Enzo Rotunno, Daan Marsmans +4
The key to optimizing spatial resolution in a state-of-the-art scanning transmission electron microscope is the ability to precisely measure and correct for electron optical aberra…
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…
Automatic alignment of an orbital angular momentum sorter in a transmission electron microscope using a convolution neural network
P. Rosi, A. Clausen, D. Weber +6
We report on the automatic alignment of a transmission electron microscope equipped with an orbital angular momentum sorter using a convolutional neural network. The neural network…
Symmetry and planar chirality of a protein measured on an angular basis in a transmission electron microscope
A. H. Tavabi, P. Rosi, R. B. G. Ravelli +16
In quantum mechanics, each conserved quantity (e.g., energy, position, linear momentum and angular momentum) is associated with a Hermitian operator. Its expected value can then be…
Towards a holographic approach to spherical aberration correction in scanning transmission electron microscopy
Vincenzo Grillo, Amir H. Tavabi, Emrah Yucelen +11
Recent progress in phase modulation using nanofabricated electron holograms has demonstrated how the phase of an electron beam can be controlled. In this paper, we apply this conce…
Domain (Grain) Boundaries and Evidence of Twin Like Structures in CVD Grown Graphene
Jinho An, Edgar Voelkl, Jiwon Suk +8
Understanding and engineering the domain boundaries in chemically vapor deposited (CVD) monolayer graphene will be critical for improving its properties. In this study, a combinati…
Effects of Negative Energy Components in the Constituent Quark Model
Peter C. Tiemeijer, J. A. Tjon
Relativistic covariance requires that in the constituent quark model for mesons the positive energy states as well as the negative energy states are included. Using relativistic qu…
