2. Electron microscope - Wikipedia

   en.wikipedia.org/wiki/Electron_microscope

   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.

3. Transmission electron microscopy - Wikipedia

   en.wikipedia.org/wiki/Transmission_electron...

   Transmission electron microscopy ( TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample as the beam is transmitted ...

4. Scanning electron microscope - Wikipedia

   en.wikipedia.org/wiki/Scanning_electron_microscope

   M. von Ardenne's. 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.

5. Photoemission electron microscopy - Wikipedia

   en.wikipedia.org/wiki/Photoemission_electron...

   Photoemission electron microscopy. Photoemission electron microscopy ( PEEM, also called photoelectron microscopy, PEM) is a type of electron microscopy that utilizes local variations in electron emission to generate image contrast. [citation needed] The excitation is usually produced by ultraviolet light, synchrotron radiation or X-ray sources.

   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 ...
