When arsenic is added as an impurity to silicon, the resulting material is

1. n-type semiconductor
2. p-type semiconductor
3. n-type conductor
4. insulator

Correct answer: n-type semiconductor

Solution

Arsenic is a pentavalent impurity, and when added to silicon, it donates extra electrons, making the material an n-type semiconductor.
