  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 low-voltage electron microscope (LVEM) is an electron microscope that is designed to operate at relatively low electron accelerating voltages of between 0.5 and 30 kV. Some LVEMs can function as an SEM, a TEM, and a STEM in a single compact instrument.

  4. 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.

  5. 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. Electron backscatter diffraction - Wikipedia

    en.wikipedia.org/wiki/Electron_backscatter...

    Electron backscatter diffraction (EBSD) is a scanning electron microscopy (SEM) technique used to study the crystallographic structure of materials. EBSD is carried out in a scanning electron microscope equipped with an EBSD detector comprising at least a phosphorescent screen, a compact lens and a low-light camera. In the microscope an ...

    Biden did not fully commute their sentences, meaning those defendants will still be required to comply with other terms such as paying restitution or being monitored by a probation officer.

  8. 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 ...
