noun
- substances added in small amounts to pure semiconductors to alter their electrical properties
Usage: technical; chemistry; electronics
Examples
- Silicon wafers require specific dopants to create computer chips.
- Boron and phosphorus are common dopants used in semiconductor manufacturing.
- The concentration of dopants determines the conductivity of the material.
- Engineers carefully control dopant levels during the fabrication process.
- Different dopants create either n-type or p-type semiconductors.
