Lesson Plan: Pure Semiconductors Physics • Third Year of Secondary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the electrical bonds in pure semiconductor materials.
Objectives
Students will be able to
- describe the motions of free electrons between atoms in an atomic lattice of a semiconducting element,
- relate the abundance of free electrons to vacancies in an atomic lattice of a semiconducting element,
- describe the effect of temperature changes and equilibrium temperature on a pure semiconductor,
- distinguish between interactions involving valence electrons and other bound electrons.
Prerequisites
Students should already be familiar with
- covalent bonding.
Exclusions
Students will not cover
- doping of semiconductors,
- quantitative modeling of electron motion.
