The drift current in a p-n junction is 2...

The drift current in a p-n junction is `2.0(mu)A`. Estimate the number of electrons crossing a cross section per second in the depletion region.

Text Solution

Verified by Experts

Given Drift Current ` = 20muA`
` = 20xx10^(-6)A.`
Both holes and electrons are moving
So,number of electrons
`(20xx10^(-6))/(2xx1.6xx10^(-19)) = 6.25xx10^13`
