The impurity added to a semiconductor to 1 make an N-type semiconductor is:
Aantimony
Bgermanium
Csilicon
Dgallium
Answer:
A. antimony
Read Explanation:
N-type semiconductors are created by doping an intrinsic semiconductor (like silicon or germanium) with a pentavalent impurity (an element with 5 valence electrons, such as antimony, phosphorus, or arsenic) to provide excess free electrons.
Germanium and silicon are intrinsic semiconductors themselves, not impurities.
Gallium is a trivalent impurity (3 valence electrons) used to make P-type semiconductors.
