P-N Junction Diode
In the case of forward biasing of p-n junction, which one of the following figures correctly depicts the direction of flow of carriers?
Show answer and solution
Answer: (b)
- In forward bias, majority carriers move towards the junction.
- Holes in the p region move right (towards the junction); electrons in the n region move left (towards the junction).
- Figure (b) shows the p-side arrow pointing right and the n-side arrow pointing left.
- So the answer is (b).
