Question

An n-type and p-type silicon can be obtained by doping pure silicon with :
  1. indium and aluminium
  2. phosphorous and indium
  3. arsenic and phosphorous
  4. aluminium and boron

A
arsenic and phosphorous
B
aluminium and boron
C
indium and aluminium
D
phosphorous and indium
Solution
Verified by Toppr

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.
