Question

Which pairing correctly identifies examples of intrinsic and extrinsic semiconductors?

Options

• Intrinsic: pure Si; extrinsic: pure Ge.

• Intrinsic: pure Si and pure Ge; extrinsic: n-type and p-type semiconductors.

• Intrinsic: carbon; extrinsic: pure Si and pure Ge.

• Intrinsic: n-type and p-type semiconductors; extrinsic: pure Si and pure Ge.

Answer 1

Pure silicon and pure germanium are intrinsic semiconductor examples. n-type and p-type semiconductors are extrinsic examples.
