QFET
A quantum field-effect transistor (QFET) or quantum-well field-effect transistor (QWFET) is a type of MOSFET (metal–oxide–semiconductor field-effect transistor) that takes advantage of quantum tunneling to greatly increase the speed of transistor operation by eliminating the traditional transistor's area of electron conduction which typically causes carriers to slow down by a factor of 3000. The result is an increase in logic speed by a factor of 10 with a simultaneous reduction in component power requirement and size also by a factor of 10. It achieves these things through a manufacturing process known as rapid thermal processing (RTP) that uses ultrafine layers of construction materials. The letters "QFET" also currently exist as a trademarked name of a series of MOSFETs produced by Fairchild Semiconductor (compiled in November 2015) which contain a proprietary double-diffused metal–oxide–semiconductor (DMOS) technology but which are not, in fact, quantum-based (the Q i ...

List Of MOSFET Applications
upright=1.6, gate oxide">insulating layer (pink). The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET), also known as the metal–oxide–silicon transistor (MOS transistor, or MOS), is a type of insulated-gate field-effect transistor (IGFET) that is fabricated by the controlled oxidation of a semiconductor, typically silicon. The voltage of the covered gate determines the electrical conductivity of the device; this ability to change conductivity with the amount of applied voltage can be used for amplifying or switching electronic signals. The MOSFET is the basic building block of most modern electronics, and the most frequently manufactured device in history, with an estimated total of 13sextillion (1.3 × 1022) MOSFETs manufactured between 1960 and 2018. It is the most common semiconductor device in digital and analog circuits, and the most common power device. It was the first truly compact transistor that could be miniaturized and ...
