Lesson Plan: Semiconductor Diodes Physics
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to model a semiconductor diode as a junction between n-type and p-type doped semiconductors.
Objectives
Students will be able to
- describe the motion of free electrons and vacancies through a PN junction,
- define the depletion layer of a PN junction,
- describe the effect of applying an external voltage across a PN junction in the forward and reverse directions on the motion of free electrons and vacancies through the junction.
Prerequisites
Students should already be familiar with
- doped semiconductors.
Exclusions
Students will not cover
- transistors.
