Can a programmable phase plate serve as an aberration corrector in the transmission electron microscope (TEM)? University of Antwerp
Current progress in programmable electrostatic phase plates raises questions about their usefulness for specific applications. Here, we explore different designs for such phase plates with the specific goal of correcting spherical aberration in the transmission electron microscope (TEM). We numerically investigate whether a phase plate could provide down to 1 angstrom ngstrom spatial resolution on a conventional uncorrected TEM. Different design ...
Quantifying atomic structures using neural networks from 4D scanning transmission electron microscopy (STEM) datasets University of Antwerp
Nanoscience and nanotechnologies are of immense importance across many fields of science and for numerous practical applications. In this context, scanning transmission electron microscopy (STEM) and 4D-STEM are among the most powerful characterization methods at the atomic scale. Annular dark-field (ADF)-STEM can be used to quantify atomic structures in 3D by counting atoms based on a single projection image. In 4D-STEM a full diffraction ...

New evidence on the origin of ‘bee structures’ on bitumen and oils, by atomic force microscopy (AFM) and confocal laser scanning microscopy (CLSM) Vrije Universiteit Brussel University of Antwerp
Bitumen is a complex mixture whose composition–structure-property relationships are not well-understood. Therefore, it is essential to understand which components may develop microstructures, how and when these features appear, and if they are initiated or influenced by other components. Many studies have reported so-called bee structures as well as other phases on bitumen surfaces. A large number of observations point towards the ...
Application of Atomic Force (AFM), Environmental Scanning Electron (ESEM) and Confocal Laser Scanning Microscopy (CLSM) in bitumen University of Antwerp
Undoubtedly bitumen’s viscoelastic performance has received much attention in the literature. Especially, the oxidative ageing phenomenon of bitumen has been studied by several scholars from different physicochemical and mechanical perspectives due to its direct impact on asphalt performance. The microstructural patterns observed with ageing utilising different microscopic techniques have not remained unexplored, and an increasing interest has ...
Voids in Kesterites and the Influence of Lamellae Preparation by Focused Ion Beam for Transmission Electron Microscopy Analyses Hasselt University
Kesterite solar cells based on Cu2ZnSnS4 and Cu2ZnSnS4 (CZTSe) are potential future candidates to be used in thin-film solar cells. The technology still has to he developed to a great extent and for this to happen, high levels of confidence in the characterization methods are required, so that improvements can he made on solid interpretations. In this study, we show that the interpretations of one of the most used characterization techniques in ...
Structural and electrical characterization of carbon nanotube interconnects by combined transmission electron microscopy and scanning spreading resistance microscopy KU Leuven
The use of carbon nanotubes (CNT) as interconnects in future integrated circuits (IC) is being considered as a replacement for copper. As this research needs also innovative metrology solutions, we have developed a combined approach for the plane-view analysis of CNT integrated in contact holes where transmission electron microscopy (TEM) enables the quantitative measurement of density and structure of the CNT and where scanning spreading ...
Deep convolutional neural networks to restore single-shot electron microscopy images University of Antwerp
Advanced electron microscopy techniques, including scanning electron microscopes (SEM), scanning transmission electron microscopes (STEM), and transmission electron microscopes (TEM), have revolutionized imaging capabilities. However, achieving high-quality experimental images remains a challenge due to various distortions stemming from the instrumentation and external factors. These distortions, introduced at different stages of imaging, hinder ...
An integrated electron microscopy study of prismatic and multiple sets of fine extinction bands in vein-quartz KU Leuven
Since the end of the nineteenth century fine extinction bands (FEBs) in quartz have been extensively studied by means of a polarized light microscope (PLM), universal-stage, and transmission electron microscopy (TEM). The last decade FEBs are additionally studied by electron backscatter diffraction orientation imaging (EBSD) on a scanning electron microscope (SEM) and cathodoluminescence (CL) spectroscopy on an electron probe micro-analyzer ...
