Question

Consider a $n$ -type semiconductor in which $n_{e}$ and $n_{h}$ are number of electrons and holes, respectively. [2025]

(A) Holes are minority carriers

(B) The dopant is a pentavalent atom

(C) $n_{e} n_{h} \neq n_{i}^{2}$
(where $n_{i}$ is number of electrons or holes in semiconductor when it is intrinsic form)

(D) $n_{e} n_{h} \geq n_{i}^{2}$

(E) The holes are not generated due to the donors

(3)

(A) $n_{e}$ type semiconductor holes are minority carriers and $e^{-}$ are majority carriers.

(B) Dopant are pentavalent atom.

(C) $n_{e} \cdot n_{h} = n_{i}^{2}$ for intrinsic semiconductor.

(E) In $n$ type semiconductor, primary source of holes generation are thermal excitation.
