Semiconductor
A semiconductor works by allowing certain voltages to pass through a circuit and not others. The simplest semiconductor is a diode.
Silicon Germanium
Silicon?
coefficient means that something is efficient for many uses
That is an example of a symbol.
Silicon the element is used in electronicsto make microchips. Si is a semiconductor.
Metal Oxide Semiconductor. Usually used when referring to a specific type of transistor which uses this type of semiconductor material: the Field Effect Transistor (FET).
That is an example of a symbol.
A Shockley diode uses a metal-semiconductor junction instead of a p-n semiconductor-semiconductor junction. This results in a device with a much lower forward bias voltage drop and much faster switching times.
A semiconductor laser is a type of laser which utilizes a semiconductor as its Photon source, rather than a gas (Argon, CO2, Etc...) laser which uses inert gas as an active medium. Many physicists and engineers consider a semiconductor laser a type of "Solid-State" or "Two-State" LASER.
It is to measure the amount of mass something has- the unit, for example, can be grams.
