Quantum Wavefront Shaping with a 48-element Programmable Phase Plate for Electrons
Chu-Ping Yu, Francisco Vega Ibáñez, Armand Béché +1
We present a 48-element programmable phase plate for coherent electron waves produced by a combination of photolithography and focused ion beam. This brings the highly successful c…
Event driven 4D STEM acquisition with a Timepix3 detector: microsecond dwell time and faster scans for high precision and low dose applications
Daen Jannis, Christoph Hofer, Chuang Gao +4
Four dimensional scanning transmission electron microscopy (4D STEM) records the scattering of electrons in a material in great detail. The benefits offered by 4D STEM are substant…
Reducing electron beam damage through alternative STEM scanning strategies. Part I -- Experimental findings
Abner Velazco, Daen Jannis, Armand Béché +1
The highly energetic electrons in a transmission electron microscope (TEM) can alter or even completely destroy the structure of samples before sufficient information can be obtain…
Evaluation of different rectangular scan strategies for STEM imaging
Abner Velazco, Magnus Nord, Armand Béché +1
STEM imaging is typically performed by raster scanning a focused electron probe over a sample. Here we investigate and compare three different scan patterns, making use of a progra…
Strain measurement in semiconductor FinFET devices using a novel moiré demodulation technique
Viveksharma Prabhakara, Daen Jannis, Armand Béché +2
Moiré fringes are used throughout a wide variety of applications in physics and engineering to bring out small variations in an underlying lattice by comparing with another referen…
