Definition
- Noun:
- A conductor made with semiconducting material: A device, such as a transistor or integrated circuit, that is fabricated from a material with semiconducting properties and is used to control electrical current.
- A substance whose electrical conductivity is intermediate between that of a metal and an insulator: A material, such as silicon or germanium, which conducts electricity more effectively than an insulator but less effectively than a pure conductor. Its conductivity can be increased by raising its temperature or by adding specific impurities.
Usage Examples
- Noun:
- The modern computer industry is built on the silicon semiconductor.
- Germanium was one of the first materials used as a semiconductor in early transistors.
- The factory specializes in the production of semiconductor chips for consumer electronics.
Advanced Usage
- "Semiconductor industry": The economic sector concerned with the research, design, and manufacture of semiconductor devices and components.
- He works in the semiconductor industry, developing new microprocessors.
- "Semiconductor physics": The branch of physics that studies the properties and behavior of semiconductors.
- Her research focuses on semiconductor physics and quantum dots.
