What type of charge carriers are predominant in n-type semiconductors? (2020)
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 usually have more electrons than the semiconductor material.
Step 4: Recognize that the extra electrons from the dopants are free to move. This means they can carry electric current.
Step 5: Conclude that in n-type semiconductors, the predominant charge carriers are these free electrons.
