Lesson: Semiconductors Physics • 9th Grade

In this lesson, we will learn how to describe the properties of semiconductor materials and describe how diodes are constructed.

Lesson Plan

Students will be able to

state what a semiconductor is,
state how the resistance of common pure semiconductors changes with temperature,
recall which elements are pure semiconductors,
state what doping is,
state what a p-type semiconductor is,
state what an n-type semiconductor is,
recall some elements that can be used as dopants for p-type and n-type semiconductors,
state what a p–n junction is,
recall that diodes are p–n junctions.
