History of Transistors;Part-1

 

Fed up with the large power consumption and low reliability of vacuum tubes director of research, Kelly, at bell laboratories assigned William Shockley to investigate 1. Introduction to Transistorson semiconductors to replace these tubes. John Bardeen, Walter Brattain conducted experiments under the guidance of Shockley. William Shockley experimented on field –effect amplifier but failed. But later John Bardeen, Walter Brattain researched and discovered that electrons form a barrier on the surface which is unknown until then. This breakthrough leads to the discovery of first transistor.
