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…
Reducing electron beam damage through alternative STEM scanning strategies. Part II -- Attempt towards an empirical model describing the damage process
D. Jannis, A. Velazco, A. Béché +1
In this second part of a series we attempt to construct an empirical model that can mimick all experimental observations made regarding the role of an alternative interleaved scan…
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…
Various Compressed Sensing Set-Ups Evaluated Against Shannon Sampling Under Constraint of Constant Illumination
Wouter Van den Broek, Bryan W. Reed, Armand Béché +3
Under the constraint of constant illumination, an information criterion is formulated for the Fisher information that compressed sensing measurements in optical and transmission el…
