Description

Dope the semiconductor to create a diode. Watch the electrons change position and energy.

Sample Learning Goals

Recognize that the battery is the driving force in a circuit.
Describe how n and p dopants change the structure of electron energy levels in a semiconductor.
Explain why an np junction acts as a diode, allowing current to flow one way but not another.
