  2. Electron-beam physical vapor deposition - Wikipedia

    en.wikipedia.org/wiki/Electron-beam_physical...

    Electron-beam physical vapor deposition, or EBPVD, is a form of physical vapor deposition in which a target anode is bombarded with an electron beam given off by a charged tungsten filament under high vacuum. The electron beam causes atoms from the target to transform into the gaseous phase.

  3. Deposition (geology) - Wikipedia

    en.wikipedia.org/wiki/Deposition_(geology)

    Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.

  4. Electron-beam technology - Wikipedia

    en.wikipedia.org/wiki/Electron-beam_technology

    Electron-beam machining is a process in which high-velocity electrons are concentrated into a narrow beam with a very high planar power density. The beam cross-section is then focused and directed toward the work piece, creating heat and vaporizing the material. Electron-beam machining can be used to accurately cut or bore a wide variety of metals.

  5. Physical vapor deposition - Wikipedia

    en.wikipedia.org/wiki/Physical_vapor_deposition

    Sputter deposition: a glow plasma discharge (usually localized around the "target" by a magnet) bombards the material sputtering some away as a vapor for subsequent deposition. Pulsed electron deposition: a highly energetic pulsed electron beam ablates material from the target generating a plasma stream under nonequilibrium conditions.

  6. Electron beam-induced deposition - Wikipedia

    en.wikipedia.org/wiki/Electron_beam-induced...

    Electron-beam-induced deposition (EBID) is a process of decomposing gaseous molecules by an electron beam leading to deposition of non-volatile fragments onto a nearby substrate. The electron beam is usually provided by a scanning electron microscope , which results in high spatial accuracy (potentially below one nanometer) and the possibility ...

  7. Sedimentary rock - Wikipedia

    en.wikipedia.org/wiki/Sedimentary_rock

    Sedimentary rocks are types of rock that are formed by the accumulation or deposition of sediments, ie. mineral or organic particles, at Earth's surface , followed by cementation . Sedimentation is the collective name for processes that cause these particles to settle in place.

  8. Sedimentology - Wikipedia

    en.wikipedia.org/wiki/Sedimentology

    The aim of sedimentology, studying sediments, is to derive information on the depositional conditions which acted to deposit the rock unit, and the relation of the individual rock units in a basin into a coherent understanding of the evolution of the sedimentary sequences and basins, and thus, the Earth's geological history as a whole.

  9. Low-energy plasma-enhanced chemical vapor deposition

    en.wikipedia.org/wiki/Electromagnetically...

    Plasma (argon-only on the left, argon and silane on the right) inside a prototype LEPECVD reactor at the LNESS laboratory in Como, Italy.. Low-energy plasma-enhanced chemical vapor deposition (LEPECVD) is a plasma-enhanced chemical vapor deposition technique used for the epitaxial deposition of thin semiconductor (silicon, germanium and SiGe alloys) films.
