MCQ
In an intrinsic semiconductor, conductivity is :
- ✓Low at room temperature
- BAverage
- CHigh at room temperature
- DZero at room temperature
✓
Answer
Correct option: A.
Low at room temperature
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.
Thus, its conductivity increases with temperature. Hence, in intrinsic semiconductor conductivity is low at room temperature.
