MCQ
In an intrinsic semiconductor, conductivity is:
- ALow at room temperature
- BAverage
- CHigh at room temperature
- DZero at room temperature
✓
Answer
- Low at room temperature
Explanation:
In intrinsic semiconductors, n = p. Hence, at room temperature, no free electrons are available for conduction. If the temperature is increased, the covalent bonds will break and electrons will be freed, each electron will leave behind a hole and capture a new hole the process will continued and charge flows through intrinsic semiconductor.
Thus, its conductivity increases with temperature. Hence, in intrinsic semiconductor conductivity is low at room temperature.
