FE SEM
Field-emission scanning electron microscopy (FESEM) is a type of SEM that provides higher resolution imaging than conventional SEM. FESEM works by focusing an electron beam onto a small area of the sample surface, and detecting the secondary electrons emitted from the sample.
How It Works
- An electron beam is focused onto the sample’s surface.
- The beam scans the surface.
- The scattered electrons are detected.
- The detected electrons are converted into an image.
