Semiconductors

A semiconductor is often defined as an electrical conductor that has a conductivity intermediate between that of an insulator and that of a metal. Some of the properties, which we now associate with semiconductors, have been known for a century or more. Little use was made of these properties, however, until the first decade of the last century, when practical semiconductor detectors were developed for radio reception.

Engineers and scientists turned their attention to semiconductors more than 40 years ago. They saw in them a means of solving an old engineering problem, namely, that of direct conversion of heat into electricity without boilers or machines.

The most important among the semiconductor devices, the transistors, were invented in 1948. Their invention and development resulted in the expanded use of semiconductor devices of all kinds. Semiconductor devices can usually perform all the elementary functions of oscillation, amplification, modulation and demodulation, rectification, etc. with greater economy of cost, space, and power, than can other devices such as vacuum tubes and relays. Semiconductor devices are used in measuring techniques, automatics, computers, radio and TV sets. A new industry – helioengineering* - has appeared. Solar batteries are successfully operating on sputniks and spaceships.

NOTES: * helioengineering – гелиотехника
