Question
Name one impurity each, which when added to pure Si, produces (i) n-type and (ii) p-type semiconductor.
Solution
(i) On adding As (Arsenic) to pure Si, we get n-type semiconductor.
(ii) P-type semiconductor can be obtained by doping In (Indium) to pure silicon.
(ii) P-type semiconductor can be obtained by doping In (Indium) to pure silicon.
