Question

Consider a n-type semiconductor in which $n_{e}$ and $n_{h}$ are number of electrons and holes, respectively.
(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 Choose the correct answer from the options given below :

TestHub · Accepted Answer

(A) n 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.
