Encyclopedia > Ballistic transistor

A ballistic transistor is a high-speed electronic switching device through which electrons flow unimpeded, without being slowed down by collisions with atoms as they are in a conventional transistor. The ballistic transistor is (as of 2004) still in the experimental stage of development. Look up Electronic in Wiktionary, the free dictionary Electronic can refer to many things: Objects related to electronics The band Electronic. ... Properties The electron (sometimes called negatron; commonly represented as e−) is a subatomic particle. ... Properties For alternative meanings see atom (disambiguation). ... Through hole transistors (tape measure marked in centimeters) The transistor is a solid state semiconductor device which can be used for amplification, switching, voltage stabilisation, signal modulation and many other functions. ... 2004 is a leap year starting on Thursday of the Gregorian calendar. ...


Two main techniques have emerged for creating a ballistic MOSFET (a type of field-effect transistor). The earliest idea was to control the oxidation process by which the insulating layer in the MOSFET, between the gate and the channel, is created, resulting in a smoother surface that allows electrons to flow faster. This approach is being investigated by Lucent's Bell Labs [1] (http://www.bell-labs.com/news/1999/december/6/1.html). A later, more radical, technique is to use atom-thin carbon sheets, called graphene. This has been shown to produce ballistic conduction, but the performance of the resulting transistors has not been determined. This technique is being researched in a joint effort between the University of Manchester in the UK and the Institute for Microelectronics Technology in Chernogolovka, Russia [2] (http://physicsweb.org/articles/news/8/10/13/1). The MOSFET, or Metal-Oxide-Semiconductor Field-Effect Transistor, is by far the most common field effect transistor in both digital and analog circuits. ... The field-effect transistor (FET) is a transistor that relies on an electric field to control the shape of the nonconductive depletion layer within a semiconductor material, thus controlling the conductivity of a channel in that material. ... The most fundamental reactions in chemistry are the redox processes. ... Insulators are materials which prevent the flow of heat (thermal insulators) or electric charge (electrical insulators). ... In 1996, AT&T spun off its Systems and Technology units, along with the famous Bell Laboratories, to form a new company named Lucent Technologies (NYSE: LU). ... Bell Telephone Laboratories or Bell Labs was originally the research and development arm of the United States Bell System, and was the premier corporate facility of its type, developing a range of revolutionary technologies from telephone switches to specialized coverings for telephone cables, to the transistor. ... General Name, Symbol, Number Carbon, C, 6 Chemical series Nonmetals Group, Period, Block 14 (IVA), 2, p Density, Hardness 2267 kg/m3 0. ... Graphene is a single planar sheet of sp² bonded carbon atoms. ... University of Manchester Motto: Cognitio Sapientia Hvmanitas Knowledge, wisdom, humanity. ... Chernogolovka is a town 44km North-East from Moscow, Russia, administratively in Moscow Oblast. ...

transistor: Definition and Much More from Answers.com (5853 words)
Transistors were pivotal in the advancement of electronics because of their small size, low power requirements, low heat generation, modest cost, reliability, and speed of operation.
The transistor is considered by many to be one of the greatest inventions in modern history, ranking in importance with the printing press, automobile and telephone.
Transistors are commonly used as electronic switches, for both high power applications including switched-mode power supplies and low power applications such as logic gates.
