In a p-n junction, what is the region called where no charge carriers are present?
Correct Answer: Depletion region
- Step 1: Understand what a p-n junction is. It is a boundary between two types of semiconductor materials: p-type (positive) and n-type (negative).
- Step 2: Know that in a p-n junction, charge carriers are electrons (negative) and holes (positive).
- Step 3: When the p-type and n-type materials are joined, electrons from the n-type region move to the p-type region and recombine with holes.
- Step 4: This movement of charge carriers creates a region where there are no free charge carriers left.
- Step 5: This area with no charge carriers is called the depletion region.
