The discovery of electricity fundamentally changed day-to-day life. Yet after electricity''s discovery, scientists worked to find the best way to harness electrical currents. Today, semiconductors are known as the key components of transistors and integrated circuits. Semiconductors shows how Michael Faraday paved the way for three men (John Bardeen, William Shockley, and Walter Brattain) to invent transistors, changing history forever. The book investigates semiconductors'' role in cutting edge technology and explains how semiconductors work through diagrams and full-color photos.
