Negatively charged
Positively charged
Neutral
None of these
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.
