⚠️ Common Exam Traps & Conceptual Pitfalls

Students frequently answer "electrons only" by analogizing to metals, overlooking that intrinsic semiconductors have equal concentrations of electrons and holes and that both carrier types participate in current flow (even doped material retains minority carriers). Remember to consider both electrons and holes when describing semiconductor conduction.

Electric conduction in a semiconductor takes place due to
