Pioneered with the advent of the first transistor using semiconductor materials at Bell Labs by John Bardeen and Walter Brattain, semiconductors have had a monumental impact on our society. You find them at the heart of microprocessor chips as well as transistors. Anything that’s computerized or uses radio waves depends on semiconductors. Today, most semiconductor chips and transistors are created with silicon. You may have heard expressions like “Silicon Valley” and the “silicon economy,” and that’s why — silicon is the heart of any electronic device.
