An n-type and a p-type silicon semiconductor can be obtained by doping pure silicon with
Boron and arsenic respectively.
arsenic and boron respectively.
sodium and magnesium respectively.
indium and sodium respectively.
Solution
Since p-type semiconductor has holes as majority charge carriers, thus for obtaining a p-type semiconductor we have to dope pure silicon with acceptor elements of group III-A like aluminium, boron, gallium etc.
And n-type semiconductor has electrons as majority charge carriers, thus for obtaining a n-type semiconductor silicon should be doped with electron rich donor elements of V A group like phosphorous, arsenic, etc.
