The depletion region of p-n junction has a thickness of the order of

Options

A. 0.5 nm to 1 nm
B. 5 nm to 10 nm
C. 50 nm to 500 nm
D. 500 nm to 1000 nm

Answer

D

Explanation

The width of the depletion region in an unbiased p-n junction ranges from 0.5 `mu`m to 1 `mu`m. 1`mu`m = 103 nm [1 `mu`m =`10^(-6)` m and 1 nm= `10^(-9)` m].
`:.` The width varies between 500 nm to 1000 nm.
