Question: What is the depletion region in a semiconductor?

Options:

  1. A region with excess charge carriers
  2. A region with no charge carriers
  3. A region where electrons are free to move
  4. A region that conducts electricity

Correct Answer: A region with no charge carriers

Solution: 

The depletion region is an area in a semiconductor where charge carriers are absent, creating an electric field.

Questions & Step-by-Step Solutions

What is the depletion region in a semiconductor?
  • Step 1: Understand that a semiconductor is a material that can conduct electricity under certain conditions.
  • Step 2: Know that semiconductors have two types of charge carriers: electrons (negative) and holes (positive).
  • Step 3: When a semiconductor is doped (added with impurities), it creates regions with excess electrons (n-type) or holes (p-type).
  • Step 4: When n-type and p-type materials are joined together, electrons from the n-type region move to fill holes in the p-type region.
  • Step 5: This movement of charge carriers creates a region around the junction where there are no free charge carriers, called the depletion region.
  • Step 6: The depletion region has an electric field because of the fixed charges left behind when the charge carriers move.
