In an unbiased p-n junction, holes diffuse from the p-region to n-region because

A

free electrons in the n-region attract them

B

they move across the junction by the potential difference.

C

hole concentration in p-region is more a compared to n-region.

D

All the above.

Text Solution

Verified by Experts

The correct Answer is:
C
hole concentration in p-region is more a compared to n-region.
In the unbiased p-n junction, holes diffuse from the p-region to n-region because holes concentration in the p-region is high as compared to n-region.
