⚠️ Common Exam Traps & Conceptual Pitfalls

Students often equate the positive charge of holes with a net positive charge of the p‑type crystal, overlooking that each acceptor dopant creates a negatively charged ion that balances the holes, so the material remains electrically neutral at all temperatures.

A p-type semiconductor is

Multiple Choice Options
