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…
Calibrating coordinate system alignment in a scanning transmission electron microscope using a digital twin
Dieter Weber, David Landers, Chen Huang +9
In four-dimensional scanning transmission electron microscopy (4D STEM) a focused beam is scanned over a specimen and a diffraction pattern is recorded at each position using a pix…
Live Iterative Ptychography
Dieter Weber, Simeon Ehrig, Andreas Schropp +6
We demonstrate live-updating ptychographic reconstruction with ePIE, an iterative ptychography method, during ongoing data acquisition. The reconstruction starts with a small subse…
Wigner Distribution Deconvolution Adaptation for Live Ptychography Reconstruction
Arya Bangun, Paul F. Baumeister, Alexander Clausen +2
We propose a modification of Wigner Distribution Deconvolution (WDD) to support live processing ptychography. Live processing allows to reconstruct and display the specimen transfe…
Inverse Multislice Ptychography by Layer-wise Optimisation and Sparse Matrix Decomposition
Arya Bangun, Oleh Melnyk, Benjamin März +5
We propose algorithms based on an optimisation method for inverse multislice ptychography in, e.g. electron microscopy. The multislice method is widely used to model the interactio…
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…
Live processing of momentum-resolved STEM data for first moment imaging and ptychography
Achim Strauch, Dieter Weber, Alexander Clausen +8
A reformulated implementation of single-sideband ptychography enables analysis and display of live detector data streams in 4D scanning transmission electron microscopy (STEM) usin…
Next-Generation Information Technology Systems for Fast Detectors in Electron Microscop
Dieter Weber, Alexander Clausen, Rafal E. Dunin-Borkowski
The Gatan K2 IS direct electron detector (Gatan Inc., 2018), which was introduced in 2014, marked a watershed moment in the development of cameras for transmission electron microsc…
