On June 30, 1948, AT&T Bell Labs unveiled the transitor to the world, creating a spark of explosive economic growth that would lead into the Information Age. William Shockley led a team of researchers, including Walter Brattain and John Bardeen, who invented the device. Like the existing triode vacuum tube device, the transistor could amplify signals and switch currents on and off, but the transistor was smaller, cheaper, and more efficient. Moreover, it could be integrated with millions of other transistors onto a single chip, creating the integrated circuit at the heart of modern computers.
Today, most transistors are being manufactured with a minimum feature size of 60-90nm--roughly 200-300 atoms. As the push continues to make devices even smaller, researchers must account for quantum mechanical effects in the device behavior. With fewer and fewer atoms, the positions of impurities and other irregularities begin to matter, and device reliability becomes an issue. So rather than shrink existing devices, many researchers are working on entirely new devices, based on carbon nanotubes, spintronics,
molecular conduction, and other nanotechnologies.
