Vedclass · Accepted Answer

$n_e n_h = n_i^2$

Vedclass · Answer

(D) In an extrinsic semiconductor, the product of the electron concentration $(n_e)$ and the hole concentration $(n_h)$ is constant at a given temperature.This relationship is known as the Law of Mass Action.According to this law, the product of the concentrations of electrons and holes is equal to the square of the intrinsic carrier concentration $(n_i)$.Therefore, the correct relation is $n_e n_h = n_i^2$.

If $n_e$ and $n_h$ are electron and hole concentrations in an extrinsic semiconductor and $n_i$ is the intrinsic carrier concentration, then:
