    en.wikipedia.org/wiki/Charge_transport_mechanisms

    Depending on the model, increased temperature may either increase or decrease carrier mobility, applied electric field can increase mobility by contributing to thermal ionization of trapped charges, and increased concentration of localized states increases the mobility as well. Charge transport in the same material may have to be described by ...

  3. Charge carrier - Wikipedia

    en.wikipedia.org/wiki/Charge_carrier

    There are two recognized types of charge carriers in semiconductors.One is electrons, which carry a negative electric charge.In addition, it is convenient to treat the traveling vacancies in the valence band electron population as a second type of charge carrier, which carry a positive charge equal in magnitude to that of an electron.

  4. Infantry mobility vehicle - Wikipedia

    en.wikipedia.org/wiki/Infantry_mobility_vehicle

    An infantry mobility vehicle (IMV) is a four-wheel drive armored personnel carrier (APC) serving as an armed military transport, military patrol, reconnaissance or security vehicle. Those IMVs are distinct from 8-, 6-, and 4-wheeled APCs (such as the VAB ), being closer in appearance to civilian vehicles.

  5. Electron mobility - Wikipedia

    en.wikipedia.org/wiki/Electron_mobility

    The diffusion coefficient for a charge carrier is related to its mobility by the Einstein relation. For a classical system (e.g. Boltzmann gas), it reads: = where: k B is the Boltzmann constant; T is the absolute temperature; e is the electric charge of an electron

  6. Ballistic conduction - Wikipedia

    In general, carriers will exhibit ballistic conduction when where is the length of the active part of the device (e.g., a channel in a MOSFET). λ M F P {\displaystyle \lambda _{\rm {MFP}}} is the mean free path for the carrier which can be given by Matthiessen's rule , written here for electrons:
