  2. Scanning electron microscope - Wikipedia

    en.wikipedia.org/wiki/Scanning_electron_microscope

    Image of pollen grains taken on a SEM shows the characteristic depth of field of SEM micrographs M. von Ardenne's first SEM SEM with opened sample chamber Analog type SEM. 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.

  3. Electron beam-induced current - Wikipedia

    en.wikipedia.org/wiki/Electron_beam-induced_current

    Electron-beam-induced current (EBIC) is a semiconductor analysis technique performed in a scanning electron microscope (SEM) or scanning transmission electron microscope (STEM). It is most commonly used to identify buried junctions or defects in semiconductors, or to examine minority carrier properties. EBIC is similar to cathodoluminescence in ...

  4. 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 ...

  5. Electron channelling contrast imaging - Wikipedia

    en.wikipedia.org/wiki/Electron_channelling...

    Electron channelling contrast imaging (ECCI) is a scanning electron microscope (SEM) diffraction technique used in the study of defects in materials. These can be dislocations or stacking faults that are close to the surface of the sample, low angle grain boundaries or atomic steps. Unlike the use of transmission electron microscopy (TEM) for ...

  6. Electromigration - Wikipedia

    en.wikipedia.org/wiki/Electromigration

    Electromigration. Electromigration (red arrow) is due to the momentum transfer from the electrons moving in a wire. Electromigration is the transport of material caused by the gradual movement of the ions in a conductor due to the momentum transfer between conducting electrons and diffusing metal atoms.

  7. Focused ion beam - Wikipedia

    en.wikipedia.org/wiki/Focused_ion_beam

    Focused ion beam. Focused ion beam, also known as FIB, is a technique used particularly in the semiconductor industry, materials science and increasingly in the biological field for site-specific analysis, deposition, and ablation of materials. A FIB setup is a scientific instrument that resembles a scanning electron microscope (SEM).

  8. 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 ...

  9. Electron beam prober - Wikipedia

    en.wikipedia.org/wiki/Electron_Beam_Prober

    The electron beam prober (e-beam prober) is a specialized adaption of a standard scanning electron microscope (SEM) that is used for semiconductor failure analysis. While a conventional SEM may be operated in a voltage range of 10–30 keV, the e-beam Prober typically operates at 1 keV. The e-beam prober is capable of measuring voltage and ...
