What is the effect of doping a semiconductor with donor atoms?

Correct Answer: Doping a semiconductor with donor atoms increases the electron concentration, making it n-type.

Step 1: Understand what a semiconductor is. A semiconductor is a material that can conduct electricity under certain conditions, like silicon.
Step 2: Learn about doping. Doping is the process of adding impurities to a semiconductor to change its electrical properties.
Step 3: Know what donor atoms are. Donor atoms are impurities that have more electrons than the semiconductor material.
Step 4: When donor atoms are added to the semiconductor, they provide extra electrons.
Step 5: These extra electrons increase the overall number of free electrons in the semiconductor.
Step 6: The increase in free electrons makes the semiconductor more conductive.
Step 7: A semiconductor that has been doped with donor atoms is called n-type because it has more negative charge carriers (electrons).
