At room temperature, the charge carries in an intrinsic semiconductor are
Right Answer is:
Free electrons and holes
SOLUTION
- In an intrinsic semiconductor, even at room temperature, electron-hole pairs are created.
- When an electric field is applied across an intrinsic semiconductor, the current conduction takes place due to free electrons and holes.
- Under the influence of the electric field, the total current through the semiconductor is the sum of currents due to free electrons and holes.
- Though the total current inside the semiconductor is due to free electrons and holes, the current in the external wire is fully by electrons.
