A potential barrier of 0.3 V exists across a p-n junction. If the depletion region is 1 `mu`m wide, what is the intensity of electric field in this region?

A

3 `mum`

B

5 `mum`

C

7 `mum`

D

4 `mum`

Text Solution

Verified by Experts

The correct Answer is:
B

`E="dv"/"dx" therefore dx="dv"/E=0.5/10^5 = 5xx10^(-6) m= 5 mum`
