Question:

A semiconductor doped with donor impurity is which type?

Options:

p-type

n-type

intrinsic

extrinsic

Correct Answer:

n-type

Explanation:

n-type is a pentavalent impurity which gives off one electron extra. Since donor impurities have more valence electrons than the semiconductor, a semiconductor doped with donor impurities is an n-type semiconductor.
