NEET · Physics · STD 12 - 14. Semicondutor electronics
An intrinsic semiconductor is converted into \(N\)-type extrinsic semiconductor by doping it with
- A Germanium
- B Phosphorous
- C Aluminium
- D Silver
Answer & Solution
Correct Answer
(B) Phosphorous
Step-by-step Solution
Detailed explanation
When intrinsic semiconductor (Si or Ge) is doped with a pentavalent element, e.g. \(\begin{array}{ll}\text { phosphorus }( P ), & \text { a n-type extrinsic }\end{array}\) semiconductor is created because
pentavalent dopant donates one extra electron for conduction.
pentavalent dopant donates one extra electron for conduction.
