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”.
