Semiconductor

Semiconductors are crystalline or amorphous solids with distinct electrical characteristics. They are of high resistance - higher than typical resistance materials, but still of much lower resistance than insulators. Their resistance decreases as their temperature increases, which is behavior opposite to that of a metal. Finally, their conducting properties may be altered in useful ways by the deliberate introduction ("doping") of impurities into the crystal structure, which lowers its resistance but also permits the creation of semiconductor junctions between differently-doped regions of the crystal. The behavior of charge carriers at these junctions is the basis of diodes, transistors and all modern electronics.

Semiconductor devices can display a range of useful properties such as passing current more easily in one direction than the other, showing variable resistance, and sensitivity to light or heat. Because the electrical properties of a semiconductor material can be modified by controlled addition of impurities, or by the application of electrical fields or light, devices made from semiconductors can be used for amplification, switching, and energy conversion.

Semiconductor (artists)

Semiconductor (also Semiconductor Films) are British artist duo Ruth Jarman and Joe Gerhardt producing Computer animation.

History

Ruth Jarman (b. 1973) and Joe Gerhardt (b. 1972) started making art as Semiconductor in 1999. Their art uses computer animation to explore science, time, scale, and natural forces.They work in different media ranging from single and multichannel video works, sound, installations, performance and DVD releases. They are currently based in Brighton U.K. They completed a number of fellowships at The NASA Space Sciences Laboratories UC Berkeley California USA, Berwick Gymnasium Fellowship Berwick-Upon-Tweed UK and Couvent des Récollets Paris France. They have performed and exhibited in Venice Biennale, Hirshhorn Museum Smithsonian Institution Washington DC USA, Nuit Blanche Paris, Institute of Contemporary Arts London, San Francisco Museum of Modern Art, Prague Contemporary Art Festival, Careof Gallery Milan, EMAF Osnabruck, and Beaconsfield Gallery London.

Semiconductor (disambiguation)

A semiconductor is a material with electrical conductivity due to electron flow intermediate in magnitude between that of a conductor and an insulator.
