Semiconductors are materials that have electrical conductivity between that of conductors (such as metals) and insulators (such as glass). They are the foundation of modern electronics, enabling the creation of a wide range of devices from transistors and diodes to integrated circuits and solar cells. Semiconductors are typically made from elements in the fourth and fifth groups of the periodic table, such as silicon (Si) and germanium (Ge), or from compounds like gallium arsenide (GaAs).
The unique property of semiconductors is their ability to conduct electricity under certain conditions. In their
Semiconductors are used in various applications, including:
- Transistors: The basic building block of modern electronics, transistors amplify or switch electronic signals and are
- Diodes: These allow current to flow in one direction only, making them useful in rectifiers, voltage
- Integrated circuits (ICs): Also known as microchips, ICs contain millions of transistors and other components on
- Solar cells: Semiconductors are used in photovoltaic cells to convert sunlight into electricity.
The semiconductor industry is a major driver of the global economy, with significant contributions to technological
