Question

How will you drop a pure silicon crystal to obtain a p type and n type semiconductor? ​

Answer 1

Answer:

Since p-type semiconductor has holes as majority charge carriers, thus for obtaining a p-type semiconductor we have to dope a 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.
