  2. The History of the Transistor - ThoughtCo

    The team's research was about to come to a fruitless end when the last attempt to try a purer substance as a contact point lead to the invention of the first "point-contact" transistor amplifier. Walter Brattain and John Bardeen were the ones who built the point-contact transistor, made of two gold foil contacts sitting on a germanium crystal.

  3. BCS theory - Wikipedia

    BCS theory or Bardeen–Cooper–Schrieffer theory (named after John Bardeen, Leon Cooper, and John Robert Schrieffer) is the first microscopic theory of superconductivity since Heike Kamerlingh Onnes's 1911 discovery. The theory describes superconductivity as a microscopic effect caused by a condensation of Cooper pairs.

    Developed by John Bardeen, Walter Brattain, and William Shockley at the Bell Laboratories on December 23, 1947.The transistor (short for "transfer resistance") is made up of semiconductors.

  7. BJT Transistor Bias Voltage Calculator - Calculates for ...

    A Bipolar Junction Transistor (BJT) was invented in December 1947 at the Bell Telephone Laboratories by John Bardeen and Walter Brattain under the direction of William Shockley. A Bipolar Junction Transistor is a solid-state device in which the current flow between two terminals (the collector and the emitter) is controlled by the amount of ...
