Work
Amplifying electric signals proved decisive for telephony and radio. First, electron tubes were used for this. To develop smaller and more effective amplifiers, however, it was hoped that semiconductors could be used—materials with properties between those of electrical conductors and insulators. Quantum mechanics gave new insight into the properties of these materials. In 1947 John Bardeen and Walter Brattain produced a semiconductor amplifier, which was further developed by William Shockley. The component was named a “transistor”.
Nobel Prizes and laureates
Six prizes were awarded for achievements that have conferred the greatest benefit to humankind. The 12 laureates' work and discoveries range from proteins' structures and machine learning to fighting for a world free of nuclear weapons.
