STANDARD Physics Intrinsic and Extrinsic Semiconductors MCQ Question
Let nₚ and nₑ be the number of holes and conduction electrons respectively in a semiconductor. Then
nₚ > nₑ in an intrinsic semiconductor
nₚ = nₑ in an extrinsic semiconductor
nₚ = nₑ in an intrinsic semiconductor
nₑ > nₚ in an intrinsic semiconductor
Correct Answer
Detailed Explanation
In an intrinsic semiconductor, the number of holes is equal to the number of conduction electrons, hence nₚ = nₑ.
