Depletion Layer in a Reverse-biased p-n Junction
The depletion layer in a reverse-biased p-n junction is a region where there are no charge carriers due to the recombination of electrons and holes. This region acts as a barrier to the flow of current in the junction.
Explanation of the Answer
Potential is Zero
In the middle of the depletion layer of a reverse-biased p-n junction, the potential is zero. This is because the electric field in the depletion layer creates a potential difference that prevents the flow of charge carriers. Therefore, the potential in the middle of the depletion layer is at a minimum, which is zero.
Electric Field is Zero
Although there is a potential difference across the depletion layer, the electric field is not zero. The electric field is actually at a maximum in the depletion layer, as it is responsible for creating the barrier that prevents the flow of charge carriers.
Conclusion
In summary, in the middle of the depletion layer of a reverse-biased p-n junction, the potential is zero because of the electric field that creates a barrier to the flow of charge carriers. This understanding is crucial in the study of semiconductor devices and their applications in electronic circuits.
