Question : 15 of 35

Marks: +1, -0

The formation of depletion region in a p−n junction diode is due to

movement of dopant atoms
diffusion of both electrons and holes
drift of electrons only
drift of holes only

Solution: 👈: Video Solution

During formation of p−n junction, the electrons diffuse from n-side to p-side (since, electron concentration is more in n-side compared to p-side) and the holes diffuse from p-side to n-side (since, hole concentration is more in p-side compared to n-side).
