Silicon, doped with a group 5A element forms a(n) - type semiconductor. Silicon doped with a group 3A element forms a(n) - type semiconductor.

Question

Quizplus · Accepted Answer

When silicon is doped with a group 5A element (such as phosphorus), it gains an extra electron and becomes a negatively charged n-type semiconductor.
When silicon is doped with a group 3A element (such as boron), it is missing an electron and becomes a positively charged p-type semiconductor. Therefore, the correct answer is B.
