- When was the transistor invented



 

The first transistor used two closely spaced gold contacts pressed onto the surface of a slab of high-purity germanium. Scientists in the s proposed building amplifiers from semiconductors. InShockley invented the more robust junction transistor, built in Voltage applied to one contact modulated gransistor current flowing through the other, amplifying the input signal when was the transistor invented to times. John Bardeen, Walter Brattain, and William Shockley seated posed for the press in the laboratory where they built invenhed when was the transistor invented transistor.

Electronics magazine called the device a "Crystal Triode. They selected germanium material that had been treated to contain an excess of electrons, called N-type. A small change in the current through the emitter caused a larger change in the collector current. They had created a current amplifier. Bell Telephone Laboratories prepared The Transistor: Selected Reference Material on Characteristics and Applications, the first compendium of information on the transistor and its applications, for its patent licensees.

Transistors swiftly left the lab and transsitor the marketplace. Although costlier than vacuum tubes, they were ideal when portability and battery operation were important. Dhen soon appeared as switches, beginning with an experimental computer at Manchester When was the transistor invented in Licensees of Bell Labs transistor technology developed alternative manufacturing techniques to improve the performance and reduce the cost of transisstor.

The germanium devices shown here were optimized for particular applications. This logic card with germanium diodes and alloy-junction transistors from the IBM calculator was later adopted as th IBM standard format. The bit machine used источник статьи point-contact transistors and diodes. This plug-in logic card from the Philco TRANSAC Model computer used three germanium PNP surface barrier transistors. William Shockley whhen a better transistor. Bell Labs encourages transistor research.
