The potential barrier of 0.5 V exist across a p-n junction. If the dpletion region is `5.0xx10^(-7)m` wide, then the intensity of electric field in this region is ………….

A

`1.0xx10^(9)V//m`

B

`1.0xx10^(6)V//m`

C

`2.0xx0^(5)V//m`

D

`2.0xx10^(6)V//m`

Text Solution

Verified by Experts

The correct Answer is:
B
`1.0xx10^(6)V//m`
`E=(V)/(d)=(0.5)/(5.0xx10^(-7))=0.1xx10^(7)=1.0xx10^(6)(V)/(m)`
