An n-type semiconductor is

Question

An n-type semiconductor is (A) neutral (B) positively charged (C) negatively charged (D) negatively or positively charged depending on the amount of impurity added

Tardigrade Admin · Accepted Answer

The n-type semiconductor has excess of free electrons for conduction. These electrons are unbound. Since, the total number of electrons in an atom is equal to the total number of protons in the nucleus. So, n-type semiconductor is neutral.

Q. An n-type semiconductor is

neutral

positively charged

negatively charged

negatively or positively charged depending on the amount of impurity added

The $n$ -type semiconductor has excess of free electrons for conduction. These electrons are unbound. Since, the total number of electrons in an atom is equal to the total number of protons in the nucleus. So, $n$ -type semiconductor is neutral.
