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 ...

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 ...
