Question

To obtain electrons as majority charge carries in a semiconductor, the impurity mixed is (A) monovalent (B) divalent (C) trivalent (D) pentavalent

Tardigrade Admin · Accepted Answer

In a n-type semiconductor, electrons behave as majority charge carriers whereas holes reacts as minority charge carriers. It is doped with pentavalent impurity such as Sb, As, P, Bi .

Q. To obtain electrons as majority charge carries in a semiconductor, the impurity mixed is

monovalent

divalent

trivalent

pentavalent

In a $n$ -type semiconductor, electrons behave as majority charge carriers whereas holes reacts as minority charge carriers.
It is doped with pentavalent impurity such as $S b,$ $A s,$ $P,$ $B i$ .
