Question

the majority carriers in an n - type semiconductor are
select one:
o a. holes
o b. valence electrons
o c. conduction electrons
o d. protons

Explanation:

In an n - type semiconductor, doping with pentavalent impurities (like phosphorus) adds extra electrons. These extra electrons are in the conduction band and are the majority charge carriers. Holes are the majority carriers in p - type semiconductors. Valence electrons are not the majority carriers in n - type semiconductors as they are bound in the valence band. Protons are not charge carriers in semiconductors for electrical conduction. So, the majority carriers in an n - type semiconductor are conduction electrons.

Answer:

C. conduction electrons
