Answer & Solution
Answer: Option B
Solution:
An
n-type semiconductor is a type of semiconductor material in which the majority charge carriers are
electrons. These electrons are negatively charged. The term "n-type" stands for "negative type," indicating the predominant charge of the carriers.
In an n-type semiconductor, impurities are intentionally added to introduce extra electrons into the crystal lattice, creating an excess of negative charge carriers. This leads to the conductivity of the material being primarily due to the movement of electrons.
Option A: Positively charged is
not the correct answer as n-type semiconductors have an excess of negatively charged electrons, not positively charged carriers.
Option C: Electrically neutral is
not the correct answer as n-type semiconductors have an excess of electrons and are not electrically neutral.
Option D: None of the above is
not the correct answer as the correct answer is Option B: Negatively charged.
Given the options provided, the correct answer is Option B: Negatively charged.
