In a `n`-type semiconductor, which of the following statement is true?

Options

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

Answer

C

Explanation

n-type is obtained by doping the Ge or Si with pentavalent atoms. In n-type semiconductor, electrons are majority carriers and holes are minority carriers, hence
