Pre-lab Discussion Questions
Watch the video on this experiment with these questions in mind. Be prepared to discuss them with your instructor.
- What is a semiconductor?
- What is the Hall Effect?
- Explain Van Der Pauw Technique.
- How do we explain the fact that there are "free electrons" in a metal conductor? Why are there energy bands?
- What is the band gap? The valence band? The conduction band?
- How do conductors, insulators, and semiconductors differ in their energy structures?
