Question

What is the nature of n-type semiconductor?

• A. Negatively charged
• B. Positively charged
• C. Neutral
• D. None of these

Hint:

N-type semiconductors are neutral overall, even though they contain free electrons as charge carriers.

Answer 1

The Correct Option is C

Step 1: An n-type semiconductor is created by doping a pure semiconductor with elements having more electrons. 

Step 2: Despite having free electrons, the overall charge of the semiconductor remains neutral because the number of positive protons in the nuclei balances the charge.
