  2. MOSFET - Wikipedia

    en.wikipedia.org/wiki/MOSFET

    In electronics, the metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, MOS FET, or MOS transistor) is a type of field-effect transistor (FET), most commonly fabricated by the controlled oxidation of silicon. It has an insulated gate, the voltage of which determines the conductivity of the device.

  3. Bio-FET - Wikipedia

    en.wikipedia.org/wiki/Bio-FET

    Bio-FETs couple a transistor device with a bio-sensitive layer that can specifically detect bio-molecules such as nucleic acids and proteins. A Bio-FET system consists of a semiconducting field-effect transistor that acts as a transducer separated by an insulator layer (e.g. SiO 2) from the biological recognition element (e.g. receptors or probe molecules) which are selective to the target ...

    en.wikipedia.org/wiki/Molybdenum_disulfide

    The sensitivity of a graphene field-effect transistor (FET) biosensor is fundamentally restricted by the zero band gap of graphene, which results in increased leakage and reduced sensitivity. In digital electronics, transistors control current flow throughout an integrated circuit and allow for amplification and switching.

    A field-effect transistor (FET) made of monolayer MoS 2 showed an on/off ratio exceeding 10 8 at room temperature owing to electrostatic control over the conduction in the 2D channel. [94] FETs made from MoS 2, MoSe 2, WS 2, and WSe 2 have been made. All show promise not just because of their electron mobility and band gap, but because their ...

    The SB-FET (Schottky-barrier field-effect transistor) is a field-effect transistor with metallic source and drain contact electrodes, which create Schottky barriers at both the source-channel and drain-channel interfaces. [62] [63] The GFET is a highly sensitive graphene-based field effect transistor used as biosensors and chemical sensors.

  7. Depletion and enhancement modes - Wikipedia

    en.wikipedia.org/wiki/Depletion_and_enhancement...

    In field-effect transistors (FETs), depletion mode and enhancement mode are two major transistor types, corresponding to whether the transistor is in an on state or an off state at zero gate–source voltage. Enhancement-mode MOSFETs (metal–oxide–semiconductor FETs) are the common switching elements in most integrated circuits.

  8. Multigate device - Wikipedia

    en.wikipedia.org/wiki/Multigate_device

    A multigate device, multi-gate MOSFET or multi-gate field-effect transistor (MuGFET) refers to a metal–oxide–semiconductor field-effect transistor (MOSFET) that has more than one gate on a single transistor. The multiple gates may be controlled by a single gate electrode, wherein the multiple gate surfaces act electrically as a single gate ...

    MOSFET, showing gate (G), body (B), source (S), and drain (D) terminals. The gate is separated from the body by an insulating layer (pink).. The MOSFET (metal–oxide–semiconductor field-effect transistor) [1] is a type of insulated-gate field-effect transistor (IGFET) that is fabricated by the controlled oxidation of a semiconductor, typically silicon.
