2. Scanning electron microscope - Wikipedia

   en.wikipedia.org/wiki/Scanning_electron_microscope

   A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition of the sample.

3. Scanning transmission electron microscopy - Wikipedia

   en.wikipedia.org/wiki/Scanning_transmission...

   A scanning transmission electron microscope (STEM) is a type of transmission electron microscope (TEM). Pronunciation is [stɛm] or [ɛsti:i:ɛm]. As with a conventional transmission electron microscope (CTEM), images are formed by electrons passing through a sufficiently thin specimen. However, unlike CTEM, in STEM the electron beam is focused ...

4. Electron microscope - Wikipedia

   en.wikipedia.org/wiki/Electron_microscope

   An electron microscope is a microscope that uses a beam of electrons as a source of illumination. They use electron optics that are analogous to the glass lenses of an optical light microscope to control the electron beam, for instance focusing them to produce magnified images or electron diffraction patterns.

6. High-resolution transmission electron microscopy - Wikipedia

   en.wikipedia.org/wiki/High-resolution...

   High-resolution transmission electron microscopy is an imaging mode of specialized transmission electron microscopes that allows for direct imaging of the atomic structure of samples. [ 1 ] [ 2 ] It is a powerful tool to study properties of materials on the atomic scale, such as semiconductors, metals, nanoparticles and sp 2 -bonded carbon (e.g ...

7. Environmental scanning electron microscope - Wikipedia

   en.wikipedia.org/wiki/Environmental_scanning...

   The environmental scanning electron microscope (ESEM) is a scanning electron microscope (SEM) that allows for the option of collecting electron micrographs of specimens that are wet, uncoated, or both by allowing for a gaseous environment in the specimen chamber.
