Coatings are required to remove or diminish the electrical charges that promptly accumulate in a nonconducting material when examined by a high-energy electron beam. Material samples investigated at ...

The exact birth of the scanning microscope principle is not clear, as the work of numerous scientists contributed to its inception. However, it is generally accepted that the first scanning microscope ...

It’s a problem that few of us will ever face, but if you ever have to calibrate your scanning electron microscope, you’ll need a resolution target with a high contrast under an electron beam. This ...

This article has been updated in January 2024. High resolution images of microscopic samples can be obtained experimentally using Scanning Electron Transmission Microscopy (STEM). It is an effective ...

A scanning electron microscope, acquired in 2016 with a grant from the National Science Foundation, provides a powerful tool for students, faculty, and visiting researchers to study the structure and ...

STEM operates by focusing a beam of electrons into a narrow probe that is scanned across a thin specimen. As the electrons interact with the sample, they are either scattered or transmitted. The ...
