STANDARD Physics Doping MCQ Question
If nₑ and nₕ are the number of electrons are holes in a semiconductor heavily doped with phosphorus, then
nₑ >> nₕ
nₑ << nₕ
nₑ ≤ nₕ
nₑ = nₕ
Correct Answer
Detailed Explanation
Phosphorus is pentavalent, which means it donates extra electrons when used as a dopant in semiconductors, resulting in n-type semiconductors where nₑ >> nₕ.
