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 ...

With the inventions of transmission electron microscopy (TEM) in 1931 and scanning electron microscopy (SEM) shortly after in 1937, scientists gained an unprecedented ultrastructural view of the ...

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 ...

Students and faculty will soon see the world in a new light on campus. The College has won a grant to purchase a scanning electron microscope (SEM) with energy dispersive spectroscopy (EDS) ...

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 ...
