Evolution of the Transistor: Shockley, Bardeen and Brattain discover foundation of modern electronics in 1947

One of the foundational elements of all electronic devices today is the transistor, a semiconductor device including three terminals which is capable of amplifying an electric current or voltage which is applied to one of the terminals and output through another terminal. It’s no understatement to say that modern electronic devices couldn’t function without a component that can process electrical signals in the manner accomplished by a transistor. Yesterday’s transistors have largely been replaced by today’s integrated circuits, which are capable of much more complex processing of electrical signals, but the discovery of the transistor was a huge turning point in the electronics industry of the mid-20th century… April 4th marks the 67th anniversary of the issue date for one of two patents for which this trio of innovators has been inducted into the Hall of Fame.
