In which of the following statements, the obtained impure semiconductor is of \(p\)-type?
- A Germanium is doped with bismuth
- B Silicon is doped with antimony
- C Germanium is doped with gallium
- D Silicon is doped with phosphorus
Answer & Solution
Correct Answer
(C) Germanium is doped with gallium
Step-by-step Solution
Detailed explanation
A p-type semiconductor is obtained by the dopping of a trivalent atom. Gallium is trivalent element, so germanium is doped with gallium.
