What is a semiconductor commonly used for?

Semiconductors are materials that have electrical conductivity between conductors (like metals) and insulators (like rubber). They are crucial in modern electronics due to their ability to control electrical current. One of the primary applications of semiconductors is in the manufacturing of diodes and transistors.

Diodes are semiconductor devices that allow current to flow in one direction, which is fundamental in rectifying alternating current (AC) to direct current (DC). Transistors, on the other hand, can act as switches or amplifiers in electronic circuits, making them essential for virtually all modern electronic devices, including computers, smartphones, and amplifiers.

The unique properties of semiconductors enable them to be modified through doping, which enhances their electrical properties for specific applications, further underscoring their importance in electronic device manufacturing.
