What is a semiconductor?
Semiconductors are materials with conductivity properties between conductors and insulators. Common semiconductor materials include silicon (Si) and germanium (Ge). They are close to insulators in a pure state, but their conductivity can be significantly altered by doping with a small amount of impurities.
What are the main characteristics of semiconductors?
The main characteristics of semiconductors include dopability, thermal sensitivity, photosensitivity, negative resistivity temperature characteristics, and rectification. By doping different types of impurities, different types of semiconductors can be made, such as n-type semiconductors and p-type semiconductors. In addition, the conductivity of semiconductor materials varies with external conditions such as temperature and light.
How to maintain semiconductor devices?
Avoid moisture: Semiconductor devices are sensitive to humidity and should be stored in a dry environment.
Avoid heat: High temperatures may cause performance degradation or even damage to semiconductor devices, and prolonged exposure to high temperatures should be avoided.
Anti static: Semiconductor devices are susceptible to static electricity, and anti-static measures should be taken, such as wearing anti-static wristbands and using anti-static packaging.
Regular inspection: For semiconductor devices that have not been used for a long time, regular inspections and testing should be conducted to ensure their stable performance.
