Vedclass · Answer

(D) Silicon is a group $14$ element with $4$ valence electrons.To obtain an $n-$type semiconductor,we need to dope silicon with an element having more valence electrons than silicon.Elements of group $15$ have $5$ valence electrons.Therefore,adding an impurity with $5$ valence electrons creates an $n-$type semiconductor due to the presence of extra electrons.

To get an $n-$type semiconductor,the impurity to be added to silicon should have which of the following number of valence electrons?
