COMEDK · Physics · 30. Semiconductors
\(n\)-type and \(p\)-type semiconductors can be obtained by doping pure silicon, respectively with
- A arsenic, phosphorous
- B indium, aluminium
- C phosphorous, indium
- D aluminium, boron
Answer & Solution
Correct Answer
(C) phosphorous, indium
Step-by-step Solution
Detailed explanation
\(n\) - type semiconductor has electrons as majority charge carriers. So, they are obtained by doping with pentavalent atoms like phosphorous, arsenic, etc. \(p\)-type semiconductor has holes as majority charge carriers. So, they are obtained by doping with trivalent atoms like…
