- n. a component used in electronic devices consisting of three regions of at least two types of a semiconducting material, such as doped silicon, connected to each other and to three electrodes in a conducting path so as to modify the current or voltage in an electronic circuit.

As their colleagues watched with a mix of wonder and envy, they showed how their gizmo, which was dubbed a transistor, could take an electric current, amplify it, and switch it on and off.
The leak-free transistor is made from a "nano-ribbon" of graphene less than 10 nanometres wide and just a single carbon atom thick (0.1 nm).
Gordon Moore, co-founder of the company and father of the law that bears his name, called it the biggest change in transistor technology since the 1960s.
Noyce came up with the two key inventions to make a practical integrated circuit: by leaving the oxide on, one could run interconnections as metal films over the top of its devices; and one could also put structures inside the silicon that isolated one transistor from the other.
If such a transistor is cooled to just above absolute zero, -273 degrees Celsius, and is exposed to a magnetic field a million times stronger than that of the earth, the remarkable phenomenon discovered by Störmer and Tsui sixteen years ago appears.
The photo-transistor is a member of the transistor family behaving like a photo-electric cell, or maybe to you, an electric eye.
The transistor is indeed the tool we need to do the things that the future of our business requires.
But the transistor is more than just a simplified, economical replacement for a larger piece of equipment.
For example, if the engineers at Bell Laboratories had coined the word transistor and used it only in their original research reports, that would be interesting, but scarcely as important as the word's subsequent extraordinary frequency in the language, evidenced by its widespread use.
The part about "once again" reinventing the transistor is a bit far-fetched.
