TRANSISTOR postage stamps

14 stamps

This section shows stamps related to transistors. A transistor is a semiconductor device used to control the flow of electricity such as amplify a signal or (in computers) switch current on and off. Usually transistors have three or more electrical contacts, they are used in all modern electronics. A Pentium 4 microchip for example is fabricated with 42 millions of transistors and other electronic components. The transistor was invented in 1947 at Bell Labs by William Shockley, John Bardeen and Walter Brattain. They won in 1956 the Nobel Prize in Physics.
