In an n-type silicon, which of the following statements is true:

A Electrons are majority carriers and trivalent atoms are the dopants. Correct Answer Incorrect Answer
B Electrons are minority carriers and pentavalent atoms are the dopants. Correct Answer Incorrect Answer
C Holes are majority carriers and trivalent atoms are the dopants. Correct Answer Incorrect Answer
D Holes are minority carriers and pentavalent atoms are the dopants. Correct Answer Incorrect Answer

Solution

In an n-type silicon, the electrons are the majority carriers, while the holes are the minority carries. An n-type semiconductor is obtained when pentavalent atoms, such as phosphorus, are doped in silicon atoms.
