Secondary electron imaging is the most popular mode of operation of the scanning electron microscope (SEM), with myriads of images being recorded every day, many of which find their way into ...

New research from physicists at Peking University, China, suggests that some pulsars may have massive mountains on them, ...

These secondary electron images contain information on the topography of the sample. As can be seen on the left of the figure below, the beam here is scanned on top of a surface with a protrusion and ...

Typical position of the backscattered and secondary electron detectors. Secondary Electrons. In contrast, secondary electrons originate from the surface or the near-surface regions of the sample. They ...

The emitted secondary electrons provide information on specimen morphology and topography; the angle of secondary electron emission is affected by the angle of incidence. An important factor in SEM is ...

Secondary electron images of volcanic ash from a volcanic plume in the crater rim of Villarrica volcano, Chile, collected using an air filter. Scale bars - 1μm. The Ultra Plus scanning electron ...

Researchers used atomic-resolution secondary electron (SE) imaging to capture the atomic structure of the very top layer of materials to better understand the differences from its lower layers. Share: ...

Any secondary electron detected is a result of that spot’s composition, no matter where you collect them. Common detectors pick up back-scattered electrons bouncing back toward the electron source.
