Question

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

• A. p-type semiconductor
• B. n-type semiconductor
• C. n-type conductor
• D. None of the above

Answer 1

The correct option is B n-type semiconductor

When an intrinsic semiconductor such as silicon or germanium is doped with pentavalent element such as arsenic and phosphorus, it becomes n-type semiconductor.
