Q
Q: In a p-n junction, what is the region called where no charge carriers are present?
Solution:
The depletion region is the area around the p-n junction where charge carriers are depleted, creating an electric field.
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 (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.
