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.
Listed are many semiconductor scale examples for various metal–oxide–semiconductor field-effect transistor (MOSFET, or MOS transistor) semiconductor manufacturing process nodes. Timeline of MOSFET demonstrations
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 ...
In physics, the field effect refers to the modulation of the electrical conductivity of a material by the application of an external electric field. In a metal , the electron density that responds to applied fields is so large that an external electric field can penetrate only a very short distance into the material.
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.
Fairchild FQD19N10 - N-Channel QFET MOSFET 100 V, 15.6 A, 100 mΩ. A quantum field-effect transistor (QFET) or quantum-well field-effect transistor (QWFET) is a type of MOSFET (metal–oxide–semiconductor field-effect transistor) [1] [2] [3] that takes advantage of quantum tunneling to greatly increase the speed of transistor operation by eliminating the traditional transistor's area of ...
An organic field-effect transistor (OFET) is a field-effect transistor using an organic semiconductor in its channel. OFETs can be prepared either by vacuum evaporation of small molecules, by solution-casting of polymers or small molecules, or by mechanical transfer of a peeled single-crystalline organic layer onto a substrate.
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 ...
