Q: In a p-n junction, which type of charge carriers are predominant in the p-type region? (2019)
Solution:
In a p-type region, holes are the predominant charge carriers.
Steps: 5
Show Steps
Step 1: Understand what a p-n junction is. It is a boundary between two types of semiconductor materials: p-type and n-type.
Step 2: Know that p-type semiconductors are created by adding certain materials (dopants) that have fewer electrons than the semiconductor itself.
Step 3: Recognize that in p-type materials, the absence of electrons creates 'holes'.
Step 4: Realize that these holes act as positive charge carriers because they can accept electrons.
Step 5: Conclude that in the p-type region, holes are the predominant charge carriers.
