Scanning Transmission Electron Microscopy

2015
The scanning transmission electron microscope (STEM) is one of the most useful tools in many areas of atomic-scale materials science and nanocharacterization. A STEM has the ability to generate local maps of the chemical composition and electronic structure at atomic resolution, even in complex or unknown samples.

Transmission, Scanning Transmission, and Scanning Electron Microscopy

2021
The properties of magnetic materials are closely related to their microstructure and micromagnetic structures like magnetic domains and spin textures. Electron microscopy is a powerful technique to characterize such features at nanometer resolution.

Atmospheric Pressure Scanning Transmission Electron Microscopy

Nano Letters, 2010
Scanning transmission electron microscope (STEM) images of gold nanoparticles at atmospheric pressure have been recorded through a 0.36 mm thick mixture of CO, O2, and He. This was accomplished using a reaction cell consisting of two electron-transparent silicon nitride membranes.

Phase-contrast scanning transmission electron microscopy

Microscopy, 2015
This report introduces the first results obtained using phase-contrast scanning transmission electron microscopy (P-STEM). A carbon-film phase plate (PP) with a small center hole is placed in the condenser aperture plane so that a phase shift is introduced in the incident electron waves except those passing through the center hole.

Automated electron tomography with scanning transmission electron microscopy

Journal of Microscopy, 2007
SummaryWe report the successful implementation of a fully automated tomographic data collection system in scanning transmission electron microscopy (STEM) mode. Autotracking is carried out by combining mechanical and electronic corrections for specimen movement. Autofocusing is based on contrast difference of a focus series of a small sample area.

Event-responsive scanning transmission electron microscopy

Science
An ever-present limitation of transmission electron microscopy is the damage caused by high-energy electrons interacting with any sample. By reconsidering the fundamentals of imaging, we demonstrate an event-responsive approach to electron microscopy that delivers more information about the sample for a given beam current. Measuring the time to achieve

Scanning transmission electron microscopy of biological structures

Biology of the Cell, 1994
The design of the scanning transmission electron microscope (STEM) has been conceived to optimize its detection efficiency of the different elastic and inelastic signals resulting from the interaction of the high energy primary electrons with the specimen.

Quantitative Atomic Resolution Scanning Transmission Electron Microscopy

Physical Review Letters, 2008
Complete understanding of atomic resolution high-angle annular dark-field (Z-contrast) images requires quantitative agreement between simulations and experiments. We show that intensity variations can be placed on an absolute scale by normalizing the measured image intensities to the incident beam.

Scanning transmission electron microscopy of biological macromolecules

Ultramicroscopy, 1978
Our aim is to use Scanning Transmission Electron Microscopy (STEM) for research on biological macromolecules. Preliminary experiments have been carried out on a Philips EM 300 (equipped with a high resolution stage and normal hairpin cathode) with a STEMattachment.
