What type of charge carriers are present in n-type semiconductors? (2019)

Step 1: Understand what a semiconductor is. A semiconductor is a material that can conduct electricity under certain conditions.
Step 2: Learn about n-type semiconductors. N-type semiconductors are created by adding impurities (dopants) to a pure semiconductor material, like silicon.
Step 3: Identify the type of dopants used in n-type semiconductors. These dopants are usually elements from group V of the periodic table, such as phosphorus or arsenic.
Step 4: Know what happens when these dopants are added. They provide extra electrons that are free to move around, which increases the material's ability to conduct electricity.
Step 5: Conclude that in n-type semiconductors, the majority charge carriers are these extra electrons.
