Q5. Diffusion in a p-n junction is due to
Answer : Option A
Explaination / Solution:
- In n-type semiconductor, the concentration of electrons is more compared to the concentration of holes. Similarly, in p-type semiconductor, the concentration of holes is more compared to the concentration of electrons
- The first process that occurs in the p-n semiconductor is diffusion
- In the formation of the p-n junction, due to the concentration gradient across the p and the n sides, the electrons diffuse from n region to p region and the holes diffuse from p region to n region.
