Which of the following is a characteristic of p-type semiconductors? (2022)
Step 1: Understand what a semiconductor is. A semiconductor is a material that can conduct electricity under certain conditions.
Step 2: Learn about the two types of semiconductors: n-type and p-type. N-type semiconductors have extra electrons, while p-type semiconductors have extra holes.
Step 3: Know what holes are. Holes are the absence of electrons in a semiconductor, and they act like positive charge carriers.
Step 4: Identify the majority charge carriers in p-type semiconductors. In p-type semiconductors, holes are the majority charge carriers because there are more holes than electrons.
Step 5: Conclude that a characteristic of p-type semiconductors is that they have an excess of holes.
