The role of semiconductor
A semiconductor is a material between a conductor and an insulator. Its conductivity is controllable and can be changed as needed. Semiconductors have a variety of applications, including making electronic devices such as:
Electronic Devices
- ##Diode: Allows current to flow in one direction , for rectification and switching applications.
- Transistor: Amplifies or switches electronic signals and is the cornerstone of modern electronic devices.
- Integrated circuit (IC): A tiny circuit composed of millions to billions of transistors used in computers, smartphones, and other electronic devices.
- Photodiode: Converts light into electrical energy for use in solar cells and fiber optic communications.
- Light-emitting diode (LED): Convert electrical energy into light energy for lighting, displays and signals.
Other applications
In addition to electronic devices, semiconductors are also used in:
- Solar cells: Convert solar energy into electrical energy.
- Thermal appliance: Convert thermal energy into electrical energy, or electrical energy into thermal energy.
- Hall effect sensor: Measures the magnetic field.
- Varasistor: Changes its resistance as the applied voltage changes.
The wide range of applications of semiconductors is due to their controllable electrical conductivity and unique electronic properties, which enable them to perform a variety of electronic and optoelectronic functions.
